Vellemann Vertex K8400 spool mount socket

This is a replacement for the original spool mount socket which is located on the left and right side of a Vellemann Vertex K8400 printer.

If you use this together with the low fricition spool holder (https://www.thingiverse.com/thing:1067052) you can get the spool mich narrower toward the case and save a little bit of space on each side of your printer.

Screws, nuts and bearing used are the same as the original one. You can reuse these parts.
