Spool Carrier3 [6700 Bearing]

thingiverse

My Maker Select V2 hanger doesn't fit my Hatchbox spools, so I wanted a typical roller style spool carrier that uses cartridge bearings - but they all seemed designed for standard skateboard cartridge sizes, which I didn't have. Luckily, I had some 6700-2RS cartridge bearings on hand (10x15x4) commonly used in RC trucks and cycling applications, so I came up with a couple of versions until I was satisfied. This thing will grip the top of the Maker Select V2 like crazy, and each roller's halves snap together pretty snugly. Simply slip one bearing onto the 10mm post on each part, and snap the halves together. You might need to trim the lower retaining tab or remove it entirely if needed. I printed mine in PETG with 99% infill - they roll very smoothly and quietly. I thought about removing the 1mm relief for the cartridge or adding a 1mm bumper in the center of the part to align the spool, but it works fine without those extra details.
