NinjaFlex/Cheetah minimalist spool holder

A holder for the NinjaFlex/Cheetah spools.
52mm (internal spool hole) X 22 mm (out bearing diameter)


I don't like all these "universal" holders. This holder is especially for 52mm spools and 22mm 608 ball bearing (8x22x7mm).

Holder fits perfectly with some pressure (use vise or rubber hammer)


- Allows the spools to spin freely
- Must have for flexible filament
- Minimalist design, no nuts are required for spool support
- Low printing quality requirement = fast printing
