Simple sample spool holder

thingiverse

This is a holder for a sample spool of filament that can be customized to fit various hubs and spools, along with the number of arms required. To assemble this holder, you will need to print one hub and three arms (or as many arms as you have customized), then screw them together using M3 bolts. The holes in the arms are designed to hold the filament thread securely without needing a nut, although your results may vary. Drilling 2mm holes in the arms is necessary to secure the filament ends in place. Update: Version 2 of this design has corrected several dimension errors and includes angled holes in the arms for improved filament retention. Additionally, the arms are designed with more clearance, requiring nuts on the bolts to ensure a snug fit. This design was inspired by https://www.thingiverse.com/thing:2033513 but required a larger hole diameter.
