Building a Geodesic Dome with Cardboard Tubes and Laser Cut Connectors

[@majdthabit4976]

Thank you very much for your investment and sharing. You are a very professional artist. I am starting to make a similar model but smaller, and so I learned a lot from your experience. Thank you very much.

that connection is really cool! Great work! Bamboo is another light weight solution.

[@gardeningdianne]

That's one impressive structure. Well done!

Good Job, and nice looking thank you for posting.

Thanks for sharing, learned so much!

Nice work. You were talking about the hubs being too weak, one other option is to use the zip tie dome method. The tube struts will fit into the holes, done. The zip tie dome inventor is quite intelligent.

[@OOTUS]

Yup, that also looks like an easy and effective solution to design yourself a way around the critical angles of the hub connector.

[@philhewett1601]

nicely done.

thanks very much for posting about your experience.

Awesome video! I learned so much from your video, thanks so much!

Thanks dude that is awesome

Hi. Very good project. Congratulations.

Next vídeo : A Tunnel dome.

Good idea. :) But chances of organising a big event any time soon are still rather slim at this moment. I still have an idea for a video on how to virtually design these organic structures fast in Fusion but solely for rendering purposes.

Hi, nice project. Very impressive. I could see that you have spent a great deal of time with the connections. Was there a possibility of making a 6 sided hollow plate where the tubes with wood plugged end can fit/snap-in then kept in place with a flat piece that's screwed in to the hollow plate? Best.

[@OOTUS]

That could be possible, but it would have taken even more time I think. Now I had to make 61 connectors, but there are 165 struts, so you would have to make 330 plugged ends... And you still need the connector to compensate a bit for the different angles at the connecting location, it's not super crucial with metal struts, because they can flex a little bit when put together, but with a wooden connection it's probably even more likely to break...

[@JohnGuest45]

You could make a 2 part plate hub pretty easily by laminating multiple layers of kraftpaper. Place the glued sheets over a mold and consolidate them with a hydraulic press. Most of the tubes available commercially are spiral wound from recycled paper (weak) parallel wound tubes made from kraft would be many times stronger..

[@wolfgangreichl3361]

Great project!!! Did you ever think of using plastic tubes - e.g. those cheaply available for plumbing etc.??? Was this an environmental decision (against plastics)?

[@OOTUS]

I did at first, but they were more expensive, more fragile, looked worse and are indeed al lot less environmental friendly. (especially the case for PVC plastics) Plastic would be the better choice for making it rain proof, but cardboard just seemed an overal better option...

[@khandam7709]

@@OOTUS not necessarily. The cardboard tubes couldn't be reused so if one wants a reuseable option plastic tubes can last longer, and thus have a smaller environmental impact. I liked this project but the hubs seemed wayy to fragile/complex. A whole sale metal supplier sells metal in 8m lengths and it's not that expensive if you get whoelsale account.

Thanks for explaining the v designate...soccer ball

If you designed the connectors in metal and used copper tubes it might have worked better the design you made needs to be round in the 6 way and 5 way like tent companies use . If you make ones for the copper tubes or home depot metal tubes that are cheap let us know . The bolts are fine for one time instals but for repetitive ones needs the connectors like you made but metal and round in full with bolts going through to pin them . Like regular twenty by fifteens use but we need ones on the 18 degrees for 2 v any higher than that no one would use but 2 vs if proper connectors and bolts through to pin them closed for safety might pass building inspections? You looked like you were at San Sebastian where filmfest is held.

PVC pipe rather than cardboard.

nice try man.
