SeeMeCNC Artemis Dual Filament Guide

thingiverse

With over 100 retractions on dual filament prints, I consistently experienced tangles so created this solution in Fusion 360. To prevent filament from being pushed back onto the roll, you'll need approximately 65mm of PTFE tubing. After three successful prints, it's working well thus far, but I'm likely to enhance its solidity soon. Edit: Version 2 is more robust and doesn't feel fragile even when dealing with a tangled spool. Initially, I thought the first version was an excellent idea, but it had its flaws. This revised version sits above the filament and requires only a 30mm piece of PTFE tubing.
