About this 3D model

This is to create a replacement Tripod Quick Release. It amazes me how many of these shoes are lost yet the camera and tripod are not. A lot of these seem to have a 'key' so the plates are not interchangeable when they ought to be able to do so. There is an easy-access nut recess at the bottom for attaching the shoe to the camera. This should print as created without support.
