Canon EF lens to C-Mount w/ stand

This adapter uses the same EF-mount design as other projects on this site. This version includes 4x M6 thru holes on a 25 mm grid for use with small, machine-vision cameras (as shown in photo). The conical design allows the adapter to be printed without supports. The second image was taken in the lab with the setup shown in the first image.

The inner diameter of the bayonet mount is 55 mm.
