Geared Filament Guide

thingiverse

When working on multiple objects, I encountered some z-line breaks in my work. After stabilizing the frame, they were sometimes still present. My roll of filament is supported by bearings, and the filament is guided through a hole; however, things weren't always running smoothly. So, I decided to eliminate this source of resistance and designed a dual-bearing filament guide. The horizontal bearing fits snugly in both the static part and the rotor. Note that this is just a temporary solution and I have no intention of refining or upgrading it - it works effectively.

You should glue the parts since a tight fit is not enough. Press the bearing into place in the static part. Place the bus in the center hole of the other bearing. Place washers on each side of the bus and mount them all together in the frame with the m3x20mm bolt. Use washers on both the bolt-head and nut side to remove excessive stress from the plastic. Make sure the nut is pretty tight, as the frame may deform a bit. Glue the frame to the rotator. The "T" on top of the frame indicates the top. Place the frame-rotator combination into the static part. Enter the filament through the top slot (see photo). Check the pictures for the rest of the story. Have fun!
