3D Scanner - Matrix Connector?

[Brian Huey]

Hi All,

New to this Maker Community but not new to being a Maker. I'm a IoT LTE Cellular, RPI enthusiast, Python/C and 3D print dude.

I have a few ideas in mind for making a couple attachments for the Black & Decker matrix system.

But, designing the coupler attachment from scratch in CAD, in my mind, would be an exercise akin to water torture. 

Does anyone have a 3D scanner that might be able to grab a good scan of the coupler and export to STL?

Thanks.

I'd like to see one in person before I decided it was too hard to model.  There are probably some vast simplifications that you could make but still be able to couple well.  I'd be curious to see it in person.  One of the keys to modeling something like this is to really understand your critical dimensions vs asthetic / manufacturing details.  I bet we can get something modeled that would work but it wouldn't be as rounded / clean.

Are you able to come to an open house on Tuesday night?  That would be a good opportunity for members to chime in in person.

Hi Brian,
I might have just sent you an email about this.

For a part that detailed the best 3D scanning option I can provide is photogrammetry. I wish I could tell you exactly the level of precision photogrammetry models have but I haven't determined a number for that yet. At the very least my scans could provide an excellent template from which to more exactly model what you need. I've been able to scan an object and then design parts to fit around it before, but haven't tried scanning and printing moving parts.

Are you looking to model the casing or the gears within as well? If you're planning to replicate gears as well it will probably be difficult to print them in a material that withstand that kind of stress. I doubt PLA or ABS could take it very long, although there are others here who could answer that better than me.

Cheers!

Thanks Brad and Ray, for the tips! My main goal is to model the coupler which fits into the power drive unit. Then, with the coupler model, I could design my own attachments, gearing, etc. And the stress / material would depend on the application, but I agree with the comments.

Sorry that i couldn't make the open house; kids+family != free time ;-)

No worry.  Last Tuesday was rather unproductive as an open house due to the water.  I won't be there next Tuesday but I should be there the Tuesday after.
