Filament spools holder

The structure of this spool holder is very, very robust,
filament can be replaced quickly, and is very stable when printing.
This design is extremely easy to print, no support required.
The tightness of the spool holder can be controlled by adjusting the screws.

The overall design is simple. This is a work that I am very satisfied with.

I fixed the entire spool holder to the top of the printer through the screws. My printer uses the 2020 bracket. Of course, three screws are needed to lock the base on the 2020.
