Meant to be mounted to the vcore3 spool holder from rat-rig.

Mounts using 2x M6x12mm bolts and 2x M6 3030 tnuts. The coupler used is M10.

Not a difficult print, put it on the face with the arch.

The extended one roughly centers the hole in the middle of the spool. I found this will help to prevent binding. When inserting the PTFE tube have it extend a few mm out of the rear, this will also help prevent binding.
