Corner Joint for Dodecahedron

thingiverse

This is a corner joint to make a regular dodecahedron (12 pentagons) out of 3/4 inch PVC pipe. If you need a hole diameter other than 27.2 mm, you can scale the model accordingly. So-called "1/2-inch" pipe requires scaling by 80%. To make a complete dodecahedron, you'll need 20 of these. At full size, that's over a kilogram of filament, depending on your slicer settings. You'll also need 30 equal sections of pipe. This was an exercise in Fusion360 which I'm in the process of learning. The rendering was created in Blender software. 13 January 2019: New version uploaded that should provide stronger joints
