Ender 3 Filament guide

This is a filament guide I designed to use one of the many bearings i had laying around from my fpv racing hobby. it needs a m3 screw about 10-16mm long, and a 3id x8od by 4mm wide bearing found in older 2205 brushless motors for multicopters like:http://www.myrcmart.com/brushless-motor-bearing-%CE%A63%CE%A684mm-nmb-p-8357.html The roller has a guide that can be clipped in or out to allow easier filament loading. I printed it in pla and have been using it for a little while now. The screw goes through the bearing, and threads into the hole in the plastic. the bearing is pressed into the wheel. I designed this to alleviate the friction of the 90 degree angle the filament makes into the extruder specifically when printing flexible filaments, but it works well for pla and other filaments as well.
