A brief video deomonstration:

Inspired by the struggles of some printers to use cardboard spools, this device will ensure level winding of filament onto a new plastic spool.
Run with a 3/8" socket adapter. If you want to drive it using something else, there are 4 M3 screws in a 50mm square on the drive gear.
UPDATE 2023/01/23 : Added in the 50 tooth gear I forgot to upload.
Non-printed parts required:
5x 608 bearings (I used 608ZZ, but 2RS would work too)
8x M3 x 4 x 5 Heatset Inserts
2x 6x3 Neodidymium magnets
3x M3 nuts
Assorted M3 Hardware (Ranges from M3x12-M3x40, will update this soon)
Some Glue
Optional, but useful is a piece of PTFE tube (bowden tube sized, 4x2mm)
When gluing the diamond shaft together, use two of the bearings to ensure correct positioning.

No supports Required
Printed with 4 perimeters, 40% infill, 5 top and bottom layers, and no supports.
