Atomic Core - Core for 52mm (2inch) AtomicFilament.com Spool

Atomic filament makes the best filament in the US right now. Since I only use one supplier, I decided to make a core to slide in and out of the spools used. Works pretty well. Rides on two 608 bearings sitting on some threaded rod.

I think it's actually a really common size, so it should work for other spools. If you need a different size, change the dimensions in Fusion.
