SpinRings - The perfect Fidget Spinner (probably)

prusaprinters

<p>SpinRings are my take on a classic 3D printed design. A series of concentric spherical rings that print as one piece, interlocking and spinning inside of one another.</p><p>My version, built in Shapr3D, features a couple of small tweaks. First the outer ring has a concave surface making it easier to grip. A 10 week study, conducted by an independent fidget spinner testing facility, concluded that this results in 40% less accidental drops 20% of the time (except on Mondays)</p><p>This concave edge also allows the SpinRings to stand on their edge and roll, although doing this goes against the principles of fidget spinners and will lead to eternal damnation.</p><p>Finally you will find a small divot in the centre piece making it easier to locate the middle of the SpinRings while blindfolded, a common problem.</p><p>Prints fine with a 0.4 or 0.6 nozzle, standard PrusaSlicer settings. The 0.3mm tolerance between the rings should not cause problems, I've printed tons with zero stuck.</p>
