Spool Slacker

Check out the video I made for this thing: https://youtu.be/tSn4yoYjnTw

This is meant to help with the slack created by multiplexers loading and unloading filament. You will need to print two brackets, and load with this or a similar spring: https://www.ereplacementparts.com/spiral-spring-p-50189.html

Run the filament through this to keep the spools nice and tidy when using a multiplexer. I created this to help with my Prusa MMU2.

The objects were designed to be easy to print, but the slot in the peg is quite thin, so if your printer struggles with detail, you should slow down your print speeds for this.
