Improved Snap On Guide for "|Robert|'s Alternative UM2 Feeder V2"

youmagine

I designed it after using this feeder for 2.85mm filament, which led me to realize it needed some additional guidance under the extruder motor. While printing test prints with the new feeder and 1.75mm filament I encountered noise coming from the feeder due to the filament not being centered on the pressure bearing. So I adapted the additional guidance for the 2.85mm version as well. With these two modifications I can easily switch the extruder from 2.85 to 1.75 just by switching the snap-on guide. I tested the 2.85 with some prints and it works perfectly, with complete elimination of noise. The 1.75 I only tested to ensure that the feeding really works, before making my first print. Maybe this gets an updated review after the first print, but so far it looks very good. Printed at a layer height of 0.1mm with 100% infill on the side with supports intentionally even though the part would print well on the back side because this way the parts are much stronger in areas that need it: the hooks where it snaps onto the feeder and the middle part where it must bend a little when you snap on and off.
