Universal Spool Roller

This thing re-uses those v-slot wheels I took off for the polycarbonate ones. Although I've only 1kg and 3kg rolls, it should be compatible with all rolls of filament larger than 1kg.

I have had issues with other filament rollers being too weak to hold a 3kg spool so this design splits the spool's weight over 8 wheels instead of the typical 2 or 4 bearing designs. The base is also wider than usual for stability.

Mine is printed in PETG. There may be too many forces at work here to use PLA, especially if you are using 3kg+ rolls like I am.

Rubber feet can be added for extra grip.

Enjoy!
