Spool centring holder for MK3S

I was annoyed by the rocking of the spools during printing. It also caused micro ghosting on my prints. Therefore, I designed this simple spool centering device. It is placed on the existing spool holder. The conical screws do the centering.

Some photos are showing an older version. This one has a closed base with holes for grip. Take a look at the .stl files.

New Version V3 with a halved thread depth.
