Wall-Mounted Filament Roller Guide

thingiverse

I really love Holspeed's Ender 3 Pro filament guide, but when I moved my filament spool to the wall, I wanted to add some brackets to help guide it down to my printer.Their very helpful assembly instructions:You will need to print:1 - bracket,1 - ring - (print ring.stl first, if it isn't tight enough then ring-sm.stl is slightly smaller inside).2 - spacersPlus you will need:1 - 608 bearing (probably the most commonly available bearing, used for skateboard wheels and other things).1 - M4 x 16mm bolt (spare part with my Ender 3, hopefully yours too).Assembly (the photos will assist):1) Lay the ring on a flat surface and press the bearing all the way in - if you feel it isn't on tight enough then print ring-sm and use that one.2) Push a spacer into each side of the bearingIf you don't want to pull the filament out of your hotend do step 3 last.3) Fit assembled bearing into bracket, insert and tighten bolt from the front - the back hole is smaller so the bolt can cut a thread as you wind it in.4) Firmly push the bracket all the way onto the Z-axis carriage (the cutouts wrap around the axle spacer and nut).5) Ensure filament isn't tangled from the spool then feed end through roller, then into extruder feeder as per normal.
