It Spins!
thingiverse
Print-in-place Spinner (I utilized the Diamond hotend, so mine's in color) Just print and tear off the 4 small support rings from beneath the bearings. ....and loosen the bearing balls with a small screwdriver if necessary.... I used 0.3mm height per layer, but I assume better resolution will yield better results... https://www.youtube.com/watch?v=ipU1M5uahQ0&feature=youtu.be
