Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3290951.

Designed to hold spools on the side of your UM3 allowing the machine to be pushed up against a wall.

Mounts onto the UM3 using existing mounting holes. You'll need slightly longer screws however.

This feeds well for every type of filament I have tried and lays compact against the side of the UM3.

There are three versions:

• The original
• V2 - which has larger diameter spindles and a flange to keep the spools from wobbling so much.
• Small Spindle - which as a small diameter spindle but a good flange allowing to work with the few (looking at you Polyalchemy) very small diameter spool holes

This design was inspired by: https://www.thingiverse.com/thing:2827919 but I needed a much more compact footprint.
