Some recent models using 3D-printed connectors for K'nex rods. Connectors modeled in OpenSCAD using vertex angles from Great Stella.

In case anyone else is export STLs for 3D printing, the magic incantation to get Cura to read the STL correctly was: - repair it in Microsoft's 3D Tools: https://tools3d.azurewebsites.net/ - import the resulting 3MF file into Autodesk's MeshMixer, and export as ASCII STL And the results: https://img...

That worked perfectly for orientation, thank you. I'm still trying to get my slicer (3D printing CAM software) to recognize it as a solid object, but I haven't exhausted my possibilities there yet. Here's a rhombicuboctahedron, snub cube, and part of a small snub icosicosidodecahedron: https://imgur...

I just printed a lovely Snub Cube via the STL Export and my 3D printer. I'm looking for other interesting shapes to print now, and came across the Small Snub Icosicosidodecahedron (too ambitious?). My problem is getting it to set on a flattish face for printing -- preferably the 3-way symmetry axis ...

My particular addiction is building models of polyhedra using a kids' building toy called Knex. To do so, I 3D-print vertex connectors with the appropriate angles. I had some difficulty obtaining the correct angles until I found Great Stella, and Robert helpfully pointed out the Display/Show Vertex ...
