Filament Spool Holder - 628zz Bearing Assembly

thingiverse

This is a basic spool holder that utilizes four 628zz bearings. The half-sleeves are mounted on the bearings, providing an excellent guide for the filament spool. Simply mount all the bearings with the half sleeves as depicted in the picture, using either a cut m8 threaded rod or m8 bolts, and you will be fine. I have also included Sketchup files in case modifications are necessary. The extra holes in the stand primarily serve to conserve filament and reduce print times; however, they can also be used to secure the stand with m8 bolts. To ensure proper fitment of the half sleeves on the bearings, they should fit snugly. If they happen to slip, simply print the half sleeve at 99.5% infill density and you will be fine, or apply a bit of glue to the exterior of the bearing for added security.
