Replacement Filament guide for the Ultimaker 2. This guide incorporates a bearing to reduce friction while guiding the filament.
UM2 Filament Guide by Labern https://www.youmagine.com/designs/um2-filament-guide & Low friction UM2 spoolholder by IRobertI https://www.youmagine.com/designs/low-friction-um2-spoolholder
I didn’t like the way the stock Filament guide on the UM2 was fixed and added extra friction to the feeder assembly and a groove was beginning to wear into the guide also. I created one that would utilize a bearing and a more robust mounting design.
There are designs for both 608 and 626 bearings included. I have only printed and tested the 608 assembly as those are the bearing I had on hand, extra from building IRobertl’s Spoolholder. Please let me know if you use the 626 version if there are problems that need to be corrected.
I chased the M4 threaded hole with a tap but you may not need to if you print the part with a small enough layer height. All the parts should print without support except the base bracket which will require some support in the recess on the bottom side.
Remember to come back and post what you've printed as Make.
It's good for the designer and the community (that means you)!
