Sample spool

thingiverse

This spool is designed for filament samples, capable of holding a 50g sample with some extra space left over. Multiple holes are strategically placed in various locations to facilitate easy startup and secure the filament's end when not in use. To assemble the two parts, you will need three #4 x 3/8 or 1/2 sheet metal flat head Phillips screws. The spool should serve your needs well.
