Using Kapton Tape to smooth spool feed

Just a little tip idea I had for mt ‪@GratKit3D‬ #FireFly Filament Dryer
It actually reduced the friction between the spool and the hanger and allowed for smoother motion with cardboard spools especially which seemed to be wearing when doing a lot of printing.
this could also help on any other spool holder If it does not have bearings.
