GeoDome Hubs

thingiverse

I corrected the angles on my "Hexhub" designs, switching them to the correct orientation. I've also updated the STL and openSCAD files accordingly. I added base hubs to make a dome that sits flat on a surface, along with markers to indicate which holes require shorter struts for easier construction. To create this design, I took the opportunity to learn openSCAD. Here's a quick project where I tried making hubs for a GeoDome - apologies if the code looks a bit messy; it's my first attempt! You can see the full notes and instructions at simplydifferently.org/Geodesic_Dome_Notes?page=3#2V/L2. My design features low-profile hubs with 1mm walls (you can adjust the wall size in the script), along with screw holes to secure the struts to the hubs with small screws. To build a dome, you'll need 26 connectors - 20 hexagons and 6 pentagons - as well as 65 struts made from different lengths of material. Strut Breakdown: A: 35 units (100%) B: 30 units (113%) Hub Details: 5-way Penthubs: 6 units 6-way Hexhubs: 20 units You can build a full sphere by adding just six more pentagons and using 60 of each strut type - lengths A(100%) and B(113%). Sphere Requirements: Struts: A: 60x100% B: 60x113% Hubs: 5-way Penthubs: 12 units 6-way Hexhubs: 20 units My openSCAD files include 9mm holes for the struts, but you can easily change this in the script if needed.
