I wanted a minimal spinner for my Monoprice Select Mini V2 because I'm really not into all these OTT designs. This is a "boring man's" no-thrills functional spinner.

It's not the most snug fit because I know different PLAs shrink at different rates - so it might be a little loose or you may need to drill it out a bit (a 5mm drill bit would be best if you need to). With my settings it slips on fine and spins, so that was good enough for me.

I printed it on my Monoprice Select Mini V2, using 3DQF Jet Black PLA, with these settings:

• 0.131 resolution
• 20% infill
• No supports or adhesion
• 0 thrills

Print it upside down (on the head's surface) or you may get problems inside the little stump that fits to the printer.
