Ender 6 spool holder remix

Added v3 - as v2 cannot fit with my desgin of a spool for the Inslogic (not printed yet)

Added v2 - A bit longer version to support wider spools such as Inslogic, the spool holder still few millimeters away from my table plate (which is 290mm x 290mm)

I made a bit different design based on the screw from the guys below.
The idea is inversting the metal plate so it'll be possible to mount the circule cover.
It also minimizes the footprint of the spool inside the printer so the table won't hit it.
