Spool Holder for Creality Ender with 2020 extrusion frames

This is a remix of a spool holder design by Stamos. It fits 2020 (or 2040) extrusion frames. The version is meant to be used with the roller that comes standard with the Ender 3 and other Creality printers. It can be placed on the top of the frame and can be optionally secured with a M3 bolt, though in my case I did not find that to be necessary. Will need to print with supports.

UPDATE 2/23/2022
Re-tooled the holder so that the roller is on the same side as the mount, in order to add strength and stability. Also, added a duplicate with the mount and roller on the opposite side.
