Universal Spool Holder

I saw this part and used it as the inspiration for my design.

Different brand filaments have different sizes of center holes and different spool widths. This part will adjust to friction lock on to different spools and the part slides nicely over my spool holder arm with bearings. That way the center of the spool aligns with the center of the spool holder arm and reduces the amount of force needed to turn the spool.
