Thanks to the original Author, I was able to modify the P1 mount that secures the V3 bayonet to the rod. This mod uses the rest of the printable and non-printable parts from the original @KPTexan_38915 post.
You will need M4 or M5 bolt and nut to secure the V3 bayonet to the P1 mount.
The mount allows enough adjustment to get the bayonet aligned with the barrel.

This will get you to the complete mounting system for V3 bayonet.
I can't thank @KPTexan_38915 for their original work and dedication to creating something from scratch.
The author remixed this model.
