Monoprice Maker Ultimate 2 Filament Guide

thingiverse

This thing is an addition to the Monoprice Maker Ultimate 2 top mount spool holder found here: https://www.thingiverse.com/thing:4445727 If you are using the top mount spool holder you may have noticed that during retractions and moves towards the spool holder you are getting back spooled filament. This is a solution to that problem. The head of the arm has a PTFE holder integrated into it with a chamfered oval exit to allow for the filament to move at a gradual extension rate rather than a hard corner to prevent filament breakage. I have done extensive testing with PLA, CF PLA, PETG, CF PETG, ABS, CF ABS, PC, and Glow in the Dark PLA. The glow in the dark filament is by far my most brittle filament and I was able to complete a few prints but I cannot recommend this on extremely brittle filaments. I would just dial up the tension on the spool that this Thing is an addition too. The designer of the Thing this is an addition to and was inspired by (hence the design) can be found here https://www.thingiverse.com/notforeveryone/designs I have NOT tested this with flexibles... Yet I will update when I do but this Thing is a done deal in my opinion.
