I created this mount for a project I am working on. I have not yet seen a model of the Pentax K-mount that fits my camera, so I decided to create one. The mount is sturdy and locks into the camera (and unlocks ;) ) thus it can be safely used to mount lenses on your camera. I use the file a lot to create adapters and lenses for my camera.

Let me know what you made out of this thing :)
