I want to revisit this idea of 3d Printing head combs and possibly other hard drive tools. My idea is that it’s not for sale, I want to release them for free. I want to create a few models of head combs that might be the more expensive or the hardest drives to do the rebuilds on, release them for free, and other people can just go get a $200 printer and a bottle of resin and make as many as they want. 

 

I have 4x 3d Printers at this point and have been starting to design some small items not related to drives and I find that a $200 resin printers are super accurate on measurements. I can use a caliper, take a broken hard drive and measure out the dimensions on the heads in mm and then in the 3d modeling tool just say stick this piece on that piece at this height and at this length and print and so far coming out very accurate. 

 

I want to create a library and selection of parts for the head combs or other tools that people can assemble on their own. Make videos for people to learn how assemble them and make more or changes themselves for new hard drives as they come out. I would try to inspire people to share them with the rest of the world and many we make a website and database to catalog them.

 

Questions?

If you had models for a hard drive you didn’t have, would you be up for using a printer and printing your own? Making your own? Testing them? Giving them away? Helping others? Are we all just fine and happy waiting for new devices and buying them? Honestly I don’t need anything and for the effort its easier to just buy tools, but basically I am thinking of this like an open source hard drive tool community, who knows where it will go. I am getting really tired of how much things keep increasing in price, shipping is getting expensive and import fees are going up.  I am not sure how many of you are really advanced at doing this so far, and maybe can offer some insight what you think of this idea. Anybody up for this? Does anyone care? Anyone want this?

Thank you,

I think this is a great idea and the sort of open source sharing that this community needs more of. My Fusion360 skills are rudimentary at best and I only have one resin printer, but I’d be willing to contribute however I can.

Right now I need a tool to swapp platters on a wd slim

I have done the measurements and am going to try to print in a few days

no sorry

Thats a picture of the expensive one that you can buy
i put it up as my goal

i wish i could cnc that...

I plan to 3d print it with carbon fiber filament

if it cant take the force then I might have to complement it with metal bits

like the 'dowels' that engage the holes - I could find nails or screw to screw into the 3d printed part

the lockring doesnt have much surface to twist against - thats the part that will probably fail

I plan to 3d print it with carbon fiber filament - Being carbon fibre that stuff should have reasonable tensile strength. For the shaft and the collar I guess it should be sufficient.

 

if it cant take the force then I might have to complement it with metal bits - I reckon the dowels that drop down into the spindle centre most likely would need to be steel. That said 3d plastics have come a long way.

 

like the 'dowels' that engage the holes - I could find nails or screw to screw into the 3d printed part - I imagine if you heat the nail you should be able to just plunge it into the plastic and remove quickly, trim off any excess plastic on the holes then set them with superglue or similar. Either that or drill the holes out.

 

the lockring doesnt have much surface to twist against - thats the part that will probably fail - Looking at the photo the teeth that engage the lip of lock ring are quite thick. I would suggest the screw tension on the platter from the lock ring would not be that great. Carbon fibre filament sounds like it is going to be quite strong. I would make a prototype and test. I bet it will work but that's only my opinion.

 

Can't wait to see how it goes :)

Well I think if anyone has any they want to share that other can test would be the first step. I don’t want to build any that someone else has done already, so if we can get a list of what is covered and people would like to request some that are not covered then we can start with building those. Once we have a handful of sets we can figure out what is the common denominator and make objects that can be reused to make new ones. Then when we get 20 or so I will find a way to create a database that isn’t owned by a company that can take it down, or I will host it myself if needed. Its not the first time I have done this…..just first time for this purpose.

 

I think the format of the files should be like the standard ones usually shared, a zip with a readme.txt with the model of the drive its for, and tips on how it was printed, if it needs supports, etc, then a folder with files that can include OBJ files and STL files, and maybe project files if necessary.

 

Anyone have a list of drives they have them for? Anyone want to share and upload a few here to test? If they are large I will create a google drive or dropbox to start until I have enough to make a database. Let me know?

I’ve been using carbon fiber and wood filament and they are indeed stronger than PLA. However we can also go to ABS an  resin I think is actually really close to ABS. I feel like we can get close, just need a model to test.

I have started to create some in OpenSCAD because it's easy to share them and free to use. Actually I work on a website that registred users can just enter the parameters like spacing, no. of heads, ... and generate the OpenSCAD-file.

I design them so that you can 3D-print or CNC mill them.

I see there two possible problems:

1. the carbon-fiber filaments are a bit stronger but will not withstand larger forces at points like that knobs, brooves, etc.
2. FFF-printers tend to be a bit unpredictable and mess up dimentions based on various factors

I would use a cheaper chineese CNC-router and you will get better accuracy and faster production of the parts as well as a sturdy alloy-part!

Would you prefer to have GIT-repos so that everyone can contribute and fork it or would you prefer to use a website where just selected people can add data and others can vote if the headcomb / script / etc. work / fit / etc.?

While I’ve used GitHub, I don’t feel like it has the proper layout to do this. Maybe Later I’ll change my mind, but it doesn’t seem like it to me from my experience so far.

@Scott
Sounds right but in my case I guess the DB would be quite helpfull - have a look: https://opensource-data-recovery-tools.com/hardware.php

I added fast the ramp-ones. The E-type ones come later on.

I would not go with a filament printer - the surface needs a lot of work to be smooth, the printer a lot of tweaking to be acurate and in the end you invest a lot of time and still you got 2 or 3 different sized parts when you pint 5 of them.

If you want you can try a cheaper resin-printer like Anycubic Photon (worked fine in my test but working with that resin was messy) or the cheaper Photon Zero (lower resolution). Her you can see a print from ther chineese "Level2" combs: DSC_4157.jpg
You see the marks very well where the printer stopped and started again. I am quite sure that was a powder-bases printer but you get the point. I tryed some FFF-printers which are known for accuarcy and all of them failed with different filaments.

I would recommand CNC milling for 2.5D parts and resin-based printing for such complicated forms.

By luck I had today morning that video-suggestion in youtube and it demonstrate 3D-printing and the quality of parts to expect quite good: https://www.youtube.com/watch?v=_GH0ZpaTwqs&ab_channel=The8-BitGuy&t=710

Pay attention to the quite good visible layers and bare in mind that all slim parts (e.g. the part which go under the heads on an E-Type tool) will be extreamly fragile and you may experience some bending while printing. But you see the rougher texture quite well in the video and that is the max. size of parts which I personally would want to fabricate on an FFF-printer.

Even finer details I would not want to try with that printers. To show you the difference in details I found that video: https://www.youtube.com/watch?v=xDUWcQuj7VU&ab_channel=3DMN&t=400

Resin-printers have more potential but fragile thin structures (like the before mentioned thin lifter for the heads) tend to bend. When you print with resin you get out a half decent hardend part which you have to clean in alcohol and cure it after with UV light. So even when you got it printed right there is a huge danger to bend and twist fine things while removing it from the build-plate and washing left over resin away with alcohol. Here you can see what I mean: https://www.youtube.com/watch?v=4jYgyjmp6lo&ab_channel=Inventorsquare&t=270 

My ramp combs you can print quite decent with resin the E-type ones are quite tricky. 

When we move to the new lab in the middle of december I will to a complete tutorial with all endmills, settings, used software, etc. to work with the CNC 3018 and maybe also another testrun with the photon for the E-type ones. Apropos E-type. I will add them today or at least over the weekend on the website - just need to redo the OpenSCAD with parameters.

I guess looking at the plunger he made for the keyboard, it looked pretty crappy compared to what I have been doing and my carbon fiber looks a lot nicer than his. I get more detail and a lot smoother. The second is resin. I didn’t even try this is just my base, if I am trying to get better there are things I can fine tune. I also have been printing TPU, Ninjatek flex and the rubber is awesome. All my parts come out great and work perfect. I am thrilled with how close I can do and get parts smooth. Ill send photos later, I am about to leave for a week.

On the LCD printer, I have ordered a Photon Mono X which is twice the size of the model he showed. It’s a pretty big platform with a 8.9" 4K Monochrome LCD. :192mm(L*120mm(W*245mmH I already have a Mars Pro which is about what he has. I don’t think its is a messy a people say. I am pretty good at dealing with the materials with a Wash and Cure machine, its pretty clean and fast and at this point I don’t get a drop of resin on anything and I don’t even need to wear gloves anymore as it is never anywhere I don’t want it to be, so far.

For bigger parts sure - I have 3D printed a lot in my lab. But compare the size of that parts and a plunger which need to fit under a key-cap. If you want (and have time after the workshop) you could download the headcomb and print it. I am sure the ramp-ones would work fine in resin for the FFF-printer I am not sure but the print take just a few minutes so cou could give it a try...

Thank you! The E-type ones are online: https://opensource-data-recovery-tools.com/hardware.php?t=head_comb_universal_e_type

But you are right - some of your prints look really clean and maybe I was just to lazy to tweak each little thing to the max. to get better prints but I just found CNC milling faster and easier for me. I would love to see if you get the ramp-combs to run on the FFF-printer. 

As I told I am now slowly packing up my stuff and prepare to move so in the middle of dez. I will start to mill and probably print some more stuff.

Please let me know what I need to do

... it would be great if you and some of you guys would report some tested mesurements and we all could build up a database of parameters so that we all can download the right model and straight away print or mill it. I will let you know as soon as I had time to setup the DB and code a small tool to enter the params for the print.

I would love to have it as e.g. APEX - just enter the model and you get a list of combs which fit.

Long long time ago I promissed to work on them and slowly they take form. Sorry for that - corona, certification tests, moving and many more stuff keep my busy the last months.

Today I did the first successfull headswap with one of my own tools. They are still a bit rough but actually I am working on the tumbling process to round the corners. The final ones will have 1.5 or max. 2mm the 3mm ones you see in that photos are to thick!  

I am still tweaking but the light weight and small bumbs on the spacers do a great job - I shaked the bad head like a cocktail and the combs stay where they should be and don't come off so no lock pin needed to prevent accidents.

Maybe I will try to mill them also from 1.5mm aluminium or some soft metal.

@Scott - how does it look with your 3D printed ones?

Subject: Re: 3d Printed Tools

 

By luck I had today morning that video-suggestion in youtube and it demonstrate 3D-printing and the quality of parts to expect quite good: https://www.youtube.com/watch?v=_GH0ZpaTwqs&ab_channel=The8-BitGuy&t=710

 

Pay attention to the quite good visible layers and bare in mind that all slim parts (e.g. the part which go under the heads on an E-Type tool) will be extreamly fragile and you may experience some bending while printing. But you see the rougher texture quite well in the video and that is the max. size of parts which I personally would want to fabricate on an FFF-printer.

 

Even finer details I would not want to try with that printers. To show you the difference in details I found that video: https://www.youtube.com/watch?v=xDUWcQuj7VU&ab_channel=3DMN&t=400

 

Resin-printers have more potential but fragile thin structures (like the before mentioned thin lifter for the heads) tend to bend. When you print with resin you get out a half decent hardend part which you have to clean in alcohol and cure it after with UV light. So even when you got it printed right there is a huge danger to bend and twist fine things while removing it from the build-plate and washing left over resin away with alcohol. Here you can see what I mean: https://www.youtube.com/watch?v=4jYgyjmp6lo&ab_channel=Inventorsquare&t=270 

 

My ramp combs you can print quite decent with resin the E-type ones are quite tricky. 

 

When we move to the new lab in the middle of december I will to a complete tutorial with all endmills, settings, used software, etc. to work with the CNC 3018 and maybe also another testrun with the photon for the E-type ones. Apropos E-type. I will add them today or at least over the weekend on the website - just need to redo the OpenSCAD with parameters.

I would not go with a filament printer - the surface needs a lot of work to be smooth, the printer a lot of tweaking to be acurate and in the end you invest a lot of time and still you got 2 or 3 different sized parts when you pint 5 of them.

 

If you want you can try a cheaper resin-printer like Anycubic Photon (worked fine in my test but working with that resin was messy) or the cheaper Photon Zero (lower resolution). Her you can see a print from ther chineese "Level2" combs: Image removed by sender.

Well I think if anyone has any they want to share that other can test would be the first step. I don’t want to build any that someone else has done already, so if we can get a list of what is covered and people would like to request some that are not covered then we can start with building those. Once we have a handful of sets we can figure out what is the common denominator and make objects that can be reused to make new ones. Then when we get 20 or so I will find a way to create a database that isn’t owned by a company that can take it down, or I will host it myself if needed. Its not the first time I have done this…..just first time for this purpose.

 

I think the format of the files should be like the standard ones usually shared, a zip with a readme.txt with the model of the drive its for, and tips on how it was printed, if it needs supports, etc, then a folder with files that can include OBJ files and STL files, and maybe project files if necessary.

 

Anyone have a list of drives they have them for? Anyone want to share and upload a few here to test? If they are large I will create a google drive or dropbox to start until I have enough to make a database. Let me know?

I want to revisit this idea of 3d Printing head combs and possibly other hard drive tools. My idea is that it’s not for sale, I want to release them for free. I want to create a few models of head combs that might be the more expensive or the hardest drives to do the rebuilds on, release them for free, and other people can just go get a $200 printer and a bottle of resin and make as many as they want. 

 

I have 4x 3d Printers at this point and have been starting to design some small items not related to drives and I find that a $200 resin printers are super accurate on measurements. I can use a caliper, take a broken hard drive and measure out the dimensions on the heads in mm and then in the 3d modeling tool just say stick this piece on that piece at this height and at this length and print and so far coming out very accurate. 

 

I want to create a library and selection of parts for the head combs or other tools that people can assemble on their own. Make videos for people to learn how assemble them and make more or changes themselves for new hard drives as they come out. I would try to inspire people to share them with the rest of the world and many we make a website and database to catalog them.

 

Questions?

If you had models for a hard drive you didn’t have, would you be up for using a printer and printing your own? Making your own? Testing them? Giving them away? Helping others? Are we all just fine and happy waiting for new devices and buying them? Honestly I don’t need anything and for the effort its easier to just buy tools, but basically I am thinking of this like an open source hard drive tool community, who knows where it will go. I am getting really tired of how much things keep increasing in price, shipping is getting expensive and import fees are going up.  I am not sure how many of you are really advanced at doing this so far, and maybe can offer some insight what you think of this idea. Anybody up for this? Does anyone care? Anyone want this?

Thank you,

Actually I am working an a list of parameters and I hope in the next week I can update the page that you all see the parameters. If some of you spot a mistake or want to add more disks please report back. 
Some of the tools are just tested on bad drives and I am not sure if I dial in all parameters perfectly. So every feedback is very welcome!

Actually I am testing the thumbling process to round the corners and smooth the surface. I could not sleep last night and so I made the list finish and I tested some of the combs. I am still tweaking the parameters and I would call it a alpha-state but if you want to try them then you will find the parameters on the bottom of the page: https://opensource-data-recovery-tools.com/hardware.php?t=head_comb_universal_ramp

I have an associate with a 5-axis CNC ... in case that in any way helps with the process. 

If someone can do CAM / CAD files, I'll report back any info about formats, etc, if that helps.

Hope the big companies not came to use because they stop making money on us for the tools.  Right now I have to work  on a WD20EADS-11R6B1 (10 Head, 5 Platter).  As Im still a Beginner to Intermediate on Head Swaps.  At least right now I cant do a Head Swap without Head Swap Tools.  The only Company which have the tool for this model wants $500.00.  I already do Head Swaps successfully with the help of Head Swap Tools but on this model without appropiate Tool Im not going to touch it internally for the Swap.  So any help will be very appreciated for a tool based on this model I can pay a decent/reasonable price you offers and shipping for it.

Scott: 
Do you have a repo of pictures or files that I could check out in the interim to recruit some help on my end -- without being limited to my weak vocabulary / knowledge (in yet another subject) while still getting input from experts whom I believe would assist cheaply enough to where I could cover the costs on my end..?

Are there any "core components" that'd be preferably manufactured from metal ..?
Or perhaps a jig or mold that'd be helpful for manufacturing certain (repetitive) components..?
(Basically, whatever I can do to help would be an honor given all the help the group has given me.)



The people I know with high-end equipment are by proxy -- both via my closest friend in LA:
 • One of whom has a 5-axis CNC (and requires files formatted / compatible with Dassault Solidworks)
 • The other (though he has 3D printing), his real strong suit is in precision scanning if I'm not mistaken (waiting for a reply).
    Instead of spinning (which I think I recall introducing some inaccuracy (requires motion and re-integration)...
    His 3D scanning is done via stationary / precision cameras (from all requisite angles).

Thats a picture of the expensive one that you can buy

i put it up as my goal

 

i wish i could cnc that...

 

I plan to 3d print it with carbon fiber filament

 

if it cant take the force then I might have to complement it with metal bits

 

like the 'dowels' that engage the holes - I could find nails or screw to screw into the 3d printed part

 

the lockring doesnt have much surface to twist against - thats the part that will probably fail

Here is a full set of all combs - I have prepared them so, that you can engrave and mill them in one go with a 0.8mm endmill. I would recommand to use 2mm plexiglass.
When I found a method for thumbling the tools so that I get a smoother surface und rounded corners then I will send a set to Tim. 

Email me please if someone else would like to get one set to try them as well.

I would like any comments from here if the HSA is Compatible or not.  First 5 Digits of SN are same and Manufacture Date are more or less 1 month of DOB difference.  What do not catch up is for the DCM and DCX.

And Yes I received finally today my AirScience Laminar AirFlow 36" to open HDDs and work on them + have a particle counter for it + tri-nocular Microscope AmScope 3.5X to 90X and all the stuff needed to works safely internally on them.

Can't we sometimes use ones that can do more (and just extend higher ) ..?  Though -- deference to the fact I'm likely the least knowledgeable in any chat.

ER-tools have made their tools available for free.


"Hello guys! Everybody can get 3D models of my tools here: https://disk.yandex.ru/d/XG-50CoK8hEIQQ

These models are FREE. Enjoy!

P.S. Created with SolidWorks 2015 & MasterCam X9."

If you are really good with 3d modelling cad tools.
You can define the dimensions as variables.
You could set number of platters
and all the other caliper measurements and it would make the model

That would be slick.

I can share a tooI I made to remove the platter from those super thin wd's where you have to unscrew the platter 'nut'

heads = 6; // no. of heads 
handle = 0; // length of handle 
width = 3.0; // width of comb for 3D printing 
thickness = 5.5; // thikness of comb-back 

spacer_height = 2.10; // hight of the spacer == basically platter height
spacer_peak = 0.07; // hight of the peak to overcome 
spacer_distance = 1.40; // spacing between spacers (MIN. == spacer_peak * 2 + 0.3 !!!) == distance between platters - wiggle room
spacer_length = 2.60; // length of resting-area for head

Openscad is great for things like that.

Really cool that he opensourced the tools after he stopped to sell them
