Ender 3 Filament Holder for M3D Spools

I have some legacy M3D spools sitting around and they're too small for the stock filament mount that comes with the Ender 3 V2, so I made a smaller filament spool holder.

This was my first design project, so the v1 holder and nut were remixed from

and are a bit rough.

The v2 holder is a bit cleaner and was designed from scratch to fit the second generation Ender 3 V2 mounting ring.
