Filament Roller

thingiverse

This is a filament roller that requires some basic 7mm (internal diameter) bearings of your preference. Print each half on the dovetail side with supports for the bearing clips, then simply snap the bearings into place. I'm certain I came across something similar, particularly with the dovetails, but unfortunately, I've lost track of it again. If anyone can point me in the right direction, I'd be more than happy to give credit where it's due. Print the spacer flat. When completed, this model will fit a standard Amazon Basics roll of filament perfectly. I've included the Fusion 360 files for your convenience, should you need to adjust the width - simply modify the first sketch on the spacer to narrow or expand the guide as desired.
