Filament bearings spool holder for wall rail system(F-system). Can be used with 1Kg, 3Kg, 5Kg filaments.

This is a very small part and would be easier to print than other larger spool holders.

To make support not required, the shaft is split in half.
Insert the shaft through the center of the bearing and into the center of the base part.
Make two of these parts and place them on top of the rail support.

Enjoy printing!
