Magic Fidget Cube

thingiverse

This was inspired by a model that I now can't find that used mechanical hinges. I redesigned to see if it would work using flexible filament for hinges. The AutoCAD has cube size as parameter. I tried 10mm as a test and that worked fine but ended up a little fragile. The stl here is for 15mm cubes. The longer (but not thicker) hinges are more robust.
