Prusa MMU wall mount spool holder

This is a wall-mount solution for holding your spools for the Prusa MMU3. I created this because in my opinion the included spool rollers are rather annoying to use and take up way too much desk space. Rollers use 608 bearings for smooth operation, and the spools can be easily dropped in and lifted out by just picking them up as the rollers are not attached to the rest of the mount, instead sitting in channels on the triangular mounts that prevent their motion. The wall slots are designed to be screwed in using #8 screws and feature holes so that the countersunk screws can sit flush with the piece. I encourage you to use wall anchors when installing this.

I used Cold White Esun PLA+ for the wall mount pieces and the roller body, Black Prusament PETG for the brackets and roller, and Red Polymaker PETG for the roller pins. All parts were printed with 4 perimeters for extra strength.
