Star of David extruder spinner (fits MPSM et al)

For different varieties on this basic design, see also my goofball spinner and the blank spinner. A friend just got his own Monoprice Select Mini printer, and I've printed a bunch of upgrades for him. (extruder upgrade, side panel for print bed rewiring, and a wire brace for the print bed rewiring) and I was going to print him my rude extruder spinner but then I realized I could do something a little classier for once, so here we are. It's a simple coin-shaped spinner which shouldn't require supports (or not much, at least) and should print pretty well.
