HevORT spool holder

Here is my design (including the step file for modding if wanted) of a spool holder for the HevORT.

It mounts in multiple positions.

2 EA - 6000Z bearings are required (I think a printed tire type design would work as well in place of the bearing with the correct tolerances for free spinning on the pins)

When using a bearing type spool holder - it can free spin very easily. I recommend that your filament path has a Bowden guide tube somewhere in line between the spool and extruder to prevent something like a large CoreXY pulling fast and hard causing unspooling. It really depends on the location you decide to mount the holder and the length of travel for your extruder.
