Fully printed Filament spool holder

The caged roller bearings are there purely for style points. They do not need to function. They are not very smooth. I had too much faith in FDM printed bearings.

Fully printed. No need to order any screws or bearings from anywhere. Some glue is used to glue the legs and the bearings.

The heavy spool no longer needs to sit at the highest point of an Ender 3 printer. Instead in can sit anywhere else to greatly reduce the center of gravity and emotional stress.
