Ball bearing Filament spool holder

thingiverse

I'm building a custom filament spool holder that leverages some bearings I had spare (6205-1 2RS) - they measure 52mm in outer diameter, 1 inch in inner diameter, and are a sturdy 15mm thick. Luckily, these bearings fit perfectly with the filament I use (3D Spark). To facilitate quick release, I've designed a 10-start thread on the shaft and nut, allowing for effortless attachment and detachment.
