Guide fil pour support de bobine MMU2
thingiverse
The MM2 multicolour filament guiding system that comes with the spool supports is quite sophisticated but it has its drawbacks when in use: filament slipping, knots caused by joints that block insertion into the selector... In reality, a simple guide using a piece of PTFE tubing while keeping the tubes of the selector completely free works perfectly well. The proposed model is based on the model from https://www.thingiverse.com/thing:3094325, in which I removed the FESTO joint, not very useful in my opinion.
