Filament Roller Guide for Prusa i3 MK3

thingiverse

This is a filament guide for my Prusa i3 MK3; I use it along with three additional parts: * Sliding Adjustable Spool Holder (https://www.thingiverse.com/thing:3152545) * Fixed Filament Guide (https://www.thingiverse.com/thing:2987412) Together, this creates a smooth filament path. To build this guide, you'll need the following parts: * 1x 688 bearing * 1x M3x8mm socket cap screw The screw threads directly into the plastic part. A Fusion 360 archive (.f3d) is attached if you need to make any changes. The pulley is part of Sliding Adjustable Spool Holder (https://www.thingiverse.com/thing:3122540), so you will find it in that design's .f3d, but the STL is uploaded here for simplicity. The pulley could probably be made with a concave surface, but I used one I'd already created.
