20x40 (2040) Top Mount Spool Filament Holder

This design is to mount on a 20x40mm Aluminum extrusion end used on most small printer Z-Axis to permit filament pull on the extruder to be more horizontal than vertical. I found there to be too much slipping on my Tevo Michelangelo even with changing out the OEM plastic junk extruder with an all Aluminum MK8 with 40 tooth drive gear.

This almost zero (0) friction spool holder was part of the solution along with changing the 40 tooth drive gear to a 26 tooth on the MK8 Extruder.

CAUTION: Depending upon the printer it might be necessary to add weight to the printer to prevent tipping due to the center of gravity change with a full 1kg spool on the roller
