One of my coworker's kids had this cube toy that is fun to fidget with. I've tried to recreate it for 3d printing. The current photos are of the toy, not the print, until I can get it printed.
This model is still a work in progress. I'm still working on the best way to print it. Please let me know if you try to print/assemble this. I'll update once I have it working. If you want to make it, try printing the _test.stl object. That object contains enough pieces to know if your settings will work. For the instructions, 'l' means pin and 'o' means hole, so the _ollo piece has a hole, two pins next two each other, and then another hole.
To assemble the test print, snap the lose hinge to the llll piece. Make sure the hings turns freely. Then put the hinge pins through the holes in the lool piece. Finally snap the first hole of the oooo piece onto one of those two hinge pins. If this piece swivels well, you should be all set!
For each side of the cube (6 total), you'll need either:
Alternatively color_set has enough pieces to make two sides (if you maintain the original color settings) on a 150mm square bed.
The pieces with pins (llll, ollo, hinge, side_set, color_set, pin_sides) will all need supports touching the buildplate. I found that printing them this way makes the pegs much stronger than if they were vertical.
Because the pins and holes have very small tolerances, the hinges need to be printed at .1mm or finer resolution. The leg pieces can be printed at a coarser resolution, which is why I've separated the two files.
I've found at .08mm resolution, everything prints and works well at 1x scale. If you scale up to 1.5 you can go with a coaser [faster] resolution, but it produces a larger cube.
I've been using grid supports at 20% infill to support the pins works well.
