Filament Spool Holder

This filament holder is designed to be used in 2 configurations :

1. Installing the shaft on the top hole only, and the filament spool can be held by the center hole like on a rack.
2. Installing the shaft on the bottom 2 holes and the filament spool can stand and on the shafts.

In both configurations he filament holder can be used with or without ball bearings; but use ball bearings for better performance and stability (duh).

For use without ball bearings, assemble the plate so the sides with the chamfered holes are facing inwards towards the filament. This way the pin will keep the shaft from slipping off the plate.

Recommended to print the pins slanted on its head (chamfered sides)
Printing the pins vertically will result in the teeth snapping off from the head because of layer strength.
