Summary This thing was inspired from my Bearing-less fidget spinner. Check out that thing if you haven’t already! http://www.thingiverse.com/thi... I wanted to make something really interesting and complex, yet at the same time be something that I like to print. So, after about 4 1/2 hours of designing, I came up with the cube in-a cube spinner! I like to call it the Cubical spinner! The first, and best spinner for mathematical, physics-ical, and CAD-ing nerds! It is not the easiest print, whereas it requires multiple supports, and a good layer height to print optimally. But once you overcome printing, you will have the coolest fidget-er in the block! Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: Doesn't Matter Supports: Yes Resolution: .1 - .3 Infill: 10-100% Notes: Use supports from the BASE! if you use supports everywhere, it will probably screw up the holes from which the smaller cube spins... Unless you are lucky enough to own a printer with water soluble support. (looking at you, Ultimaker 3 owners...) Post-Printing Remove supports CAREFULLY! Then, if your inside cube is fused, just gently turn the rods from either side of the cube, or the disks on the outside of it. It should break free and spin fine.
