Icosahedron

Build an icosahedron from 12 hubs and 30 struts!

The node model has a big pentagon shaped base to improve bed adherence.

Struts are secured to the hubs with 10mm M3 bolts. The screws may be optional as friction seem to be enough to hold everything in place. There is 5 bolts for a node which makes 60 in total. The screw hole in the struts are undersized for self tapping.

The struts are 120mm, in order to design your own smaller or bigger struts, be advised that the screw hole center is 10mm from the edge and the section of the strut is a 6mm square.

No supports needed.

I print the nodes at 0.15mm and the struts at 0.2mm.
