These connectors are for standard 1/2" PVC Schedule 40 Pipe (.625 OD). The motivation for me was to have a "greenhouse" structure. So I designed them to distribute water.


To make a dome, you'll need 26 connectors (20 hexagons and 6 pentagons) and 65 struts (35 of length A and 30 of length B). To determine your strut lengths, use a calculator:

Hi!, excellent idea. I want to build a geodesic dome long time ago!. One question: the size is small, i need to scale? Thx in advance! Excellent work!

Very nice. Could I get your files without the extra fitting? Thanks

These STL show up really small. They need to be scaled ? Can you load the source also plse?

I'd like to try the ones without the extra fitting please.

It's really a great idea. One connector will attach many pipes that can be put in different directions.

nice design, but are these actually printable? any finished photos?

That's a good question. Is there something that leads you to think they may not be?

BTW the first iteration, before I got the idea that they could be used to distribute water, I drew them solid and without the extra fitting. If you or someone else would prefer to attempt to print those, let me know and I'll post them.

One thing that dismays me is that Thingiverse apparently doe
s not accept STEP files! :(

Best Regards

That's surprising. I upload Solidworks files. What program are using to make step files?


I use Rhino mostly.

I was not thinking deeply enough.:-[ Being new here I saw the STL facility and mistakenly thought that was it. Also I didn't see any STEP, IGES or other standard data exchange formats being used either. I guess its just incomprehensible to me why the site would be designed the way it is. i.e. saying STL when VRML would be so much better. Do you think it might be a bias induced by the RP/AM industry?

It is because the site is for 3D printing and 3D printers use STL files.
