Spool Roller
myminifactory
Attach spool rollers to secure your spools in place, as shown on this 5lb spool in use. I prefer these spool rollers because they allow me to work with a wide range of spools, each with unique dimensions. They are easy to print and accommodate all sizes seamlessly. To complete the assembly, you'll need: 4 M5 bolts, measuring at least 14mm long Bolts longer than 20mm may stick out slightly 4 M5 hex nuts Fortunately, these nuts have a secure fit thanks to their nut traps. 4 M5 bearings - I used the 605zz model with great results.
