The camera is angled down by 3 degrees. To use this you need a 15mm or so M3 bolt, and a couple of M5x8 bolts and T slot nuts. Remove the monitor bracket from the camera, the mount then fits in place of the monitor bracket.
Note the camera is mounted upside down, this is to allow the camera to be situated slightly to the left on the gantry and therefore miss the Z chain but allow the lens to be in the middle of the build plate.
To print, use build plate support to support the 3 degree tilt on the camera plate.
