Tripod To Camera Attachment

As far as i am aware most if not all tripods have this attachment, if you loose it you can't use the tripod. But you can print a new one now. This attachment fits 2 of my tripods fine, I'm not sure if they vary much on the locking mechanism from trip to tripod? Hope it is of some use to someone. You still need to get a small bolt to screw up into the camera though.
