Summary

Okay, almost universal. Basically this is a remix that allows you to put in filament spools of different widths onto the Monoprice Maker Select Mini's spool rack. This uses standard 608zz bearings. I've also added a little guide change to keep the filament spool on the spool instead of flying off sometimes like it does on the original design.

There's THREE stand designs.

MPSM Against Printer is designed for you to put right next to the printer. The filament guide naturally pulls the filament spool closer to the 3d printer, so you put this against the wall of the 3d printer closest to it. No matter what you need one of these.

Then you can print one of the two:

MPSM Stable Mover is the outside piece with a triangle backing for stability. I recommend this piece for most spools that don't span the maximum width of the spool arm.

MPSM Flat Wall is the outside piece where you put it against the metal jut of the outside end of the 3d printer spool arm for stability. It's only for the largest and weirdest sized filament spool arms, most people will never use this.
