Rob,

             When I first saw it, it reminded me of Radiolaria.  Google image search yielded amazing pictures.  Also makes me think of Volvox.

             Thaks for advice.

Dan,

 

The tricky part will be whether or not the slot widths are proportioned correctly to the thickness of the cardboard.  If the fit is a little too loose, then I would suggest just using some Elmer's glue for a permanent assembly.  Maybe use glue regardless because I think it will make it more rigid and stable.  The ball is only 2 feet in diameter and really doesn't need to be taken apart.  I had suggested painting it with day-glo paints and illuminating it with black lights.

 

This small ball has a very similar pattern to that of the larger 12 foot dome, but on this small ball I have joined the pieces in pairs.  Hopefully, the pictures I've attached below will be enough of a guide for you to assemble it.  Good luck!  And, let me know if you have any questions at all.

Congrats Robert, I can think of no better use for a model/dome then being used in such a setting....the children that experience the dome in the museum could be the next generation of inspired geodesic designers!

[Mason Cooley]

Hi Rob,

So I had your 12' dome nested parts CNC cut and they are awaiting assembly by my class soon. I had a real quick question. From the images it looks like you alternate the overlapping joining edges? Is there a pattern to this? Also, can you explain a little more about the "notches"? I think from the pics and the assembly illustration I understand how it goes up.

Thanks!

[Mason Cooley]

Excellent this is super helpful!

Yes, the row technique is a good idea we just did that with our paper origami icosohedron models.

I will get pictures up once it is together. Our plan is to add some material to it for the final presentation. The class is a foundation design course in a professional crafts program here in WNC.

Thanks!

The overlapping doesn't matter.  It's just a matter of aesthetics.  My pattern of overlapping ended of being random.

The notches are just to help differentiate the 3 types of parts and help in orienting them correctly.  In the image, the red part would be the one that has 2 notches.  And, the grey part would be the one with just 1 notch.  A notched leg of a red piece should join up with the notched leg of a grey piece.

IMPORTANT.  When assembling, start with the bottom row of the dome and complete the full row before working on the next row up.  Work your way up evenly from the base to the top.  This will make assembly so much easier.  Just ask Dan.  If you try to assemble separate sections and then join those sections together, or just start assembling randomly, the whole thing becomes unwieldy and confusing.  One full row at a time, bottom to top is the best and easiest way.

What type of class do you teach?

Good luck to you and your students and post some pictures of the process and the completed dome.  Thanks.

best regards,

Rob

Mr. Clark, 

  I am a high school art teacher/maker that has access to a CNC machine. Our class would love to build your design. We have a few questions? 

Is there a .dxf file available for download? 

Could we complete the dome to a sphere shape? 

We are excited for your response,

All the best, 

Jason Ruff

[Rudolf]

Hello Robert,
could you send me the DXF file as well?
A friend of mine wants to build a greenhouse, he saw pictures of your design on Pinterest...

Rudolf,

 

I am re-posting the DXF file for the Plywood Hex Dome.  I have not yet heard back from Jason above.  I hope he will see this posting.

The dome is only 12 feet in diameter (small for a greenhouse) because it was just a proof of concept and I designed it small to save on cost.  Also, I used very cheap 3/16" thick underlayment plywood ($14.00 per sheet), again to save cost.  Next time, I would use 3/8" (11/32) thick plywood for a sturdier dome.  The DXF pattern needs to be repeated on six sheets of 4x8 sheets of plywood to form all the pieces for a dome.

 

In the near future, I'm thinking of creating a larger 20 foot dome of the same design, but it would require ten sheets of plywood.  Also, being larger, I might design it as a 1/2 dome instead of a 5/8 dome.  If anyone is interested, let me know.  Thanks.

 

Lastly, I'm also working on hopefully a commercial flat-pack design that is a sturdier, stronger 16-foot dome that can be assembled without tools or fasteners.  I would like to name my venture "Quick Domes".  I would appreciate any ideas or feedback.

[homespun]

Robert,

    Wow!  Thanks so much.

    I won’t be doing it right away, as I am the midst of another, rather complex project, but eventually I will do it.

Dan,

 

Here's the PDF patterns (2 sheets) to make a small 14" diameter paper half dome.  It's a simplified version of the 16 foot version that I am still working on.  When assembling, just match the circular markings.  The PDF's are sized for 8-1/2 x 11 paper.  If possible, use a thick stiff weight paper.

Dan,

 

I'll post a simplified model pattern for you here in a couple of days.  It will be similar to the image below.  Using the same 5 repeating parts (3 hubs, 2 struts), you'll be able to build the model as either a 4/9, a 1/2, or a 5/9 dome. And, all three versions will sit flat on a hard surface without rocking.  Take care.

Wade,

I have a 20 foot plywood dome design that is a little different from the bent plywood dome you are looking at, if you're interested.  This design is going to be structurally stronger.  It is also a smaller frequency with less parts, but bigger openings for creating people size entrances.  There are just 4 components:  2 hubs, and 2 strut halves.  All struts are identical.  The parts are slip-fitted to form hub sub-assemblies.  Then, the hub assemblies are put together like puzzle pieces and held together with two 1/4" diameter bolts at each strut.

Next post I can provide dxf files for cnc, but first I need to finish laying the pieces out in a nesting pattern on plywood.  I have never built or tested this dome design.  You may have to play with the CAD files to adjust it for the exact thickness of plywood.  It is designed for 3/4" ply which usually comes in at .718 thickness.  I'll let you know how many sheets of plywood it should take.

best regards,

Robert

[Wade Martin]

If it helps, no need to nest as my software will handle all of that, just numbers of how many each part are required.

Robert, thanks!
That looks perfect to me, I will cut test pieces first as always... I feel like a kid at Christmas and its the middle of June :) I look forward to the email.

I've added two extra parts to form a base for the dome.  Below are images that show the dome with the base parts and also the number of each part required as well as bolts.  I also included images showing typical layout on 4x8 foot plywood.  The complete dome will require 20 full sheets of 3/4 inch thick plywood.  I'm guessing the dome will weigh in at about 600 pounds.

I think some uses for the dome might include an event space/booth at an exhibition, or a structure at burning man.  I'd like to hear other people's ideas for uses (PLEASE).

Wade, I'm sending you the dxf files in a separate e-mail.

Hello Robbert

I'm a teacher from Belgium and in my school there is a need for a greenhouse.

During STEM-class one of my students came up with your design.

We redesigned it to fit our needs:

Made it bigger(approx 16 ft), included a dooropening and attempted to make tiles to cover the openings.

In order to have an even surface for the cover, we came up with an extra connector to eliminate the overlap jpints.

Next is to design a door for it, which will be done next year.

It's not perfect, but it's done by my 16yo students (and myself) and we are proud of where we stand at this point.

We are lucky to have a factory near our school that makes polycarbonate sheets, so we made it out of 8mm thick PC they provided at a discount.

The tiles to fit the openings are 2mm thick. The pieces were cut by water-jet.

In the end we will have a high-tech greenhouse including automatic irrigation and ventilation, IoT, LED and solar panels to power it all.

We will be cooling by a underground ventilation duct.

We would like to thank you for your inspiring model and of course share our feedback.

greetings

Hello Robert, good job, I liked the design of the attached images, I would like to be able to manufacture a 5 meter diameter plywood 15mm thick, could you send me the files to make it ?. I have a cnc router and could document the construction process.

If you had it for a model of small size it would be great to be able to move forward with it, my material for model is mdf 9mm thick.

Manuel,

The two domes are very different configurations, and both are still just conceptual.  I don't yet have access to a cnc router so I haven't done much since the original conceptual design.  As you see in the photo with actual plywood parts, a gentleman named Wade initially started work on the dome, but I think work and family pulled him away from it and that's as far as he got.  I haven't pushed to see if he got any further on it.

Which dome were you interested in?  I can send you DXF part files.  Understand that you may have to tweak and adjust dimensions to get the best fit.  You will be acting as a guinea pig and risking cost of materials and time on an unproven prototype. Do you have nesting software to lay the parts out for cnc?  The size scale of parts that I send you will not be optimized to get the most pieces out of a sheet of plywood.  But, that is something you can play with in CAD software.

I look forward to hearing back from you and helping you in any way I can.

Hi Robert,

I teach a class of 25 architecture 1st year students. They would love to make one of your domes. The 20' plywood dome or the 5m one would be ideal. Could you share the dxf files for either? We do have access to a 4'x8' CNC machine.

Thanks in advance!

Dear Robert,

So nice to hear from you directly. I lived in Boston for many years, studying, working and teaching (1985-2003).

Shamim, that would be great.  I studied architecture at the Boston Architectural College.

I will finish making some slight design adjustments to the two hubs so that the dome can sit on a flat base.

It can be assembled either as a 3/8 or 5/8 dome.

the dome size will probably be scaled down from 5 meter to a 4 meter diameter so that all the pieces fit evenly onto 6 sheets of plywood.

I can send you files this weekend.

I want to recycle plastic.  I found this place https://preciousplastic.com ,but PVC is really toxic can't be melted so I got the idea I can flatten it with a heatgun and use my plotter to make a sticker(decal) and place it on the pvc and then cut it with a saw. My vinyl cutter only  cut vinyl ... I want a x-carve but for now I just have this option. It is a lot of work ... But I need to figure out if your design will work with the PVC pipes one they is flattened. If not I will use plywood instead. Thank you again for offer you help.

Send some pics when you finish your pyramid.

A group of folks down in Texas are about to try to make a sphere using this layout.  

Then we are going to attach it to a larger sculpture.

I'm pretty excited our lead found this thread in this group because this look super fun and whatnot.  

Or a grueling torture session.  

Wooo!

I'll try to see if I can build one out of Coroplast campaign signgs. Finished the paper model to see how everything will fit. Thanks for the template Robert.

[lemondealc]

Hey Robert. I spent 3-hours laser cutting a tortuga dome. I was certain I had all the dimensions just right (I scaled down for a smaller dome and thinner material), but in the end the slots were like 1/32 too small and pieces wouldn't fit together. I got all the pieces to fit on three 4ftx4ft boards. Here are some pics of the cut outs. I'm still working on this. Just wanted to give you an update.

that actually looks really RAD'!

I would be willing to make one, if i had the plans to make it 4x bigger. this would be a better way to be preped for storage since it can be taken down, and compactly stored and reused on next site.

I feel pcv pipe is not an option im too fond of. like in the pictures you provided it can be preinstaled in sections or stored that way as well.

I just think 4x bigger space inside because, it would give 4 sections to have like a workshop space, lecture, tea station, and would give a bit more hight and room space to put up art.

all of the project builds look nice, but with the bigger wood ones is one bolting pieces together while the other system is a slide in and lock in place type?

i lean more towards using the fasteners more, thought may be more work, i feel it plays on a security of safty in windy conditions.

What kind of wood is being used in the projects?

sorry for the questions, just think this is super nice' Thanks for sharing again (=

I was really happy with the quality of the cut. I decided to sand down the slots and try putting part of it together. I was able to sand enough to use single stuts that were duct taped together. Check out the photos. I'll definitely try to build this again. I'm not sure when I'll have access to a laser cutter again. 

As for your questions:

A scaled up version would fit on three 4' x 4' boards. I actually ended up nesting too many hubs so I might have been able to fit on two boards...Maybe. As for how much I could scale up, I don't know. I'd have to experiment. I could get the current design to fit on two boards if I cut the struts from a thicker material and nested all those on one board, and then I would have nested the hubs on another boards.

I eliminated the holes because I was trying to save cutting time/travel (It took about 3+ hours the way it is). I had planned on gluing the pieces together. Or I could have used duct tape too. I just didn't need the holes for the smaller version.

lemondealc,

Your cnc layout on the three boards looks very tight and efficient.  Frustrating about the slots being slightly too tight.  If you scale it up a tiny bit, will the layout still fit on the three boards, or will you have to go to a fourth?  Also, looking at the strut pieces, I did not see the two holes that should be there for assembly.  Did that get missed or do you have another plan for connection?  See the picture below with the two holes circled in blue.  Otherwise, awesome job.  I'm hoping by end of summer, after I've got a heating system and electrical finished in my ongoing house build, to get a cnc machine myself.  I'm looking at the 33x33 Shapeko.

I did it. I had to double up the pieces because a single layer didn't hold up. It isn't strong or can carry any significant loads, but it supports itself well. The signs were free after an election. My costs were the zip-ties and the laser.

The signs were in A0 (120x84) so having a large cut volume was essential. It took about 8-10 minutes to cut each one and I used 21. You don't need very much power if you do it in multiple passes. Your are essentially cutting two sheets 3mm apart. Either go slow, so that the beam can cute the second layer, org go twice.

[Michelle DeFrance]

It was a grueling torture session!

But worth it!

We shrunk it to about 10' diameter, built a little more than the dome, but not a whole ball, and attached it to the art project (it's Sisyphus's boulder).

You can just make out the ball here: https://www.burningflipside.com/featured_art/11051

Sorry posting from my phone and I couldn't attach anything.

This is our first build of it.  We has some fun getting it on that ladder.

Our event discourages photos with people in them, so there aren't a lot of photos of it I can share.  This is one without people....

Of course it is just after we set the thing on fire.

Hi Robert, hope you're well.

I love this latest version of your design. Has anyone actually built a full sized version of it yet? I'd like to have a go if possible, my kids are very excited by the prospect! I have access to a cnc if you would be kind enough to send the dxf files for this. 

Many thanks,

Sorry, this was referring to the 20ft dome!

20 ft plywood dome parts count.jpg

[Adam]

That looks superb. I like the idea of a light sandwich compression joint to make it stiffer. I'm sure they'd love it! Is it simply scalable in your software? I really like the idea of using small components on a small Cnc from offcuts of ply. 

I use sketchup for modelling...is yours done in solidworks? 

Any and all dxf's of both designs would be great so I can have a play with tolerances etc...the guys at the workshop think I'm a bit nuts for doing this haha!

Shamim, that would be great.  I studied architecture at the Boston Architectural College.

I will finish making some slight design adjustments to the two hubs so that the dome can sit on a flat base.

It can be assembled either as a 3/8 or 5/8 dome.

the dome size will probably be scaled down from 5 meter to a 4 meter diameter so that all the pieces fit evenly onto 6 sheets of plywood.

I can send you files this weekend.

Manuel,

The two domes are very different configurations, and both are still just conceptual.  I don't yet have access to a cnc router so I haven't done much since the original conceptual design.  As you see in the photo with actual plywood parts, a gentleman named Wade initially started work on the dome, but I think work and family pulled him away from it and that's as far as he got.  I haven't pushed to see if he got any further on it.

Which dome were you interested in?  I can send you DXF part files.  Understand that you may have to tweak and adjust dimensions to get the best fit.  You will be acting as a guinea pig and risking cost of materials and time on an unproven prototype. Do you have nesting software to lay the parts out for cnc?  The size scale of parts that I send you will not be optimized to get the most pieces out of a sheet of plywood.  But, that is something you can play with in CAD software.

I look forward to hearing back from you and helping you in any way I can.
