608ZZ Bearing Hanging Filament Spool Mount

Instead of using a 3D-printed arm for the spool, I decided to create a holder with a 6 inch bolt.

I designed this hanging spool mount to go under my workbench with my printers. I had lots of bearing leftover from the fidget spinner craze and decided to put them to use. Filament comes off the roll nice and smooth.
