Filament Spool Casing for Creality Ender 5

I designed a casing for filament spools, because especially with new and full spools the filament often got entangled when it slipped over the spool's outer diameter. This then led to printing failures.
The casing tends to prevent that and it fits spools with three different widths.

You'll need three M4 thread inserts for this design.
It makes use of the stock plastic nut of the Ender 5 spool holder, so you don't need to print a new one.
