Spool Roller

thingiverse

A compact roller bearing spool runner designed for easy installation at the bottom of airtight cereal containers to store rolls that are used infrequently. The filament feeds out through the pour hole. The images showcase an earlier prototype; I've updated the design by switching to a hull from a resized cylinder, making it simpler to align with the space between the two bearing mounts. You can customize the length and bearing size to fit your specific needs or available materials.
