Rectangular-ish Quick Release Tripod mount

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.
