Spool holder for UP Plus / UP Plus 2 with bearings

thingiverse

Human: Replacement filament spool holder for the UP Plus / UP Plus 2. Clips on instead of original one, a filament spool rolls smoothly and quietly on skate bearings (608). To assemble this replacement part, follow these steps: 1. Print holder (on the side) with 100% infill and five perimeters. 2. Print clip (holes up). 3. Clean support thoroughly. 4. Slide five to seven 608 bearings onto the middle rod; be careful not to break it off as it is fragile. 5. Clip on the "clip" at the end of the holder securely. 6. Replace the original spool holder with this one. This replacement part can hold a 1.5kg spool of filament easily and rolls smoothly and quietly. If you are using standard 1kg (65mm width) or 0.5kg (42mm width) spools, use the clipon-large file to also prevent the spool from sliding off the holder. The small clip is designed for larger 1.5-3kg spools that can sit on it; however, they are not fully supported by this holder.
