Hatchbox Spool Roller

thingiverse

I often swap out filaments, so I created this spool roller for my Hatchbox filaments quickly and easily. It works very smoothly and effectively reduces friction. Initially, I printed the bearing sleeves in PLA, but after mastering flexible filaments, I decided to make the bearing sleeves with NinjaTek Cheetah filament and it performs even better. Included are the base by itself, four bearings individually, one bearing alone, and the complete assembly (excluding bolts, nut, and washer). I used one-quarter inch bolts that were one-and-one-fourth inches long. I applied a quarter-inch washer on each side of the bolt holes to secure the bolt head and nut more effectively. The bearings are 608ZZ. Print Settings Rafts: No Supports: Yes Infill: 15% Notes: I minimize infill usage to save filament. I used supports for the base piece, but that's because I'm overly cautious. The only area where it might need supports is around the bolt holes. Post-Printing After Printing I applied one-quarter inch bolts that were one-and-one-fourth inches long. I used a quarter-inch washer on each side of the bolt holes to secure the bolt head and nut more effectively. The bearings are 608ZZ.
