I designed a camera arm / mount for the raspberry pi cam v2.1 which mounts directly to the structure of the Anycubic Vyper.

Simply remove the 2 bolts underneath the build plate as shown in the pictures, line up the camera arm and insert 2 longer bolts to accommodate the increased thickness (factory bolts will not have enough length to grab the threads with the extra thickness of the arms mounting plate).

Use tree supports for the camera arm @ 75° overhang angle & Place on the build plate like I did.

I also ordered an extension cable for the pi cam as the factory one was too short. I will link this below.

All designs are my own work and have been produced on Solidworks.
