Filament Spool Bearing Sleeve

My extruder motor is now spinning freely, with significantly less resistance thanks to my new spool design. This upgrade wasn't essential for the Ender 3, but it was a thrilling first step into working with Fusion 360. I picked up some affordable skateboard bearings (8mm x 22mm x 7mm) and carefully fitted them snugly into the disk. Everything was meticulously measured to ensure a perfect fit with Amazon's Basic Spools. I'm eager to add more spools as I encounter other varieties!
