Filament spool holder

Filament spool holder for spools in diameter from 145 mm to 220 mm. You can adjust the with of the holder by pushing the two parts more together. The maximum spool width can be up to 75 mm.

Also, the spool holder fits nicely on the controller box of the Creality3D - CR10s. Every other controller box with a width of 125mm will do, too.

I had 6003 ball bearings lying around. Print the part twice to have one full holder.
