Top Mount Bearing Filament Roller + Guide System
Description
This is a top rail mounted, bearing spool roller. It uses 16 (yes, that's overkill lol) 608 bearings that I had (from amazon) to create a very low friction roller. Makes changing spools so much easier too, simply remove the spool and replace with new one. The filament guide that attaches at the corner of the top rail keeps the filament aligned on its way down to the extruder. I suggest using both for best results.
