World smallest cube spinner (R188 bearing)

thingiverse

Got a bunch of those nice R188 (12.7mm x 6.35mm x 4.75mm) and some spare time. As I love little gadgets, I started a project to make a cube spinner based on a gadget I saw somewhere. Also wanted it to be tiny and well... here's a 24mm spinner cube!! Maybe it's not actually the smallest cube spinner in the universe, but at least in my house!! All parts require support (the body part requires full support). Remove carefully the supports, sand it a bit and put a drop of glue on the outer perimeter of the bearing and in the hole. Then snap-fit all together. I recommend printing parts in different colors; it should make it look cool. The pics show my first prototype. At that moment, I had only one unoccupied printer and was impatient to see it working. You know what I mean... Enjoy! Other thoughts: Maybe more convenient if the insertion hole had a cube shape to help with alignment at assembly time. Anyway, I had no problem aligning it; simply put it on a flat table and press it firmly. Do this before the glue dries, because once it happened to me... UPDATE (16-JUN-2017): Added Cap1-Keyring.stl part to make it become a keyring or necklace as requested by a friend.
