Building toy connector ball

thingiverse

This thing connects other things, namely sticks. Crazy Forts is a brand of stick and ball construction toy, but I was out of balls so I designed a replacement. It's not exactly the same as the original, using a standard geometric shape instead - no trademark issues to worry about. The design is technically a rhombicuboctahedron, allowing for a huge number of combinations to build with. Holes have been added to the shape, but they might need a bit of reaming out to fit perfectly. Luckily, I haven't had to do much tweaking at all. I printed it in carbon fiber because I had some on hand and liked the black color. Something that polishes nicely would be even better, though. The corners are slightly larger than the original, but everything functions just as well. The basic geometry model was borrowed from Agustin Rossi's work on GrabCAD: https://grabcad.com/library/rhombicuboctahedron-2 All design work was done in Autodesk Fusion 360 on my MacBook and printed out using a Kodama Trinus.
