Needed a ¾" 20 pitch screw for the Modular Tripod Handle designed by @FredrikHamrebjorkDes ( https://www.printables.com/model/247650-modular-tripod-handle/ ) so I bashed one together in Fusion360.
It's designed to be a tight fit through the hole of the Tripod thread module rev1.3mf so that it doesn't fall out, you will have to push it through with a bit of force from the bottom.
I included a 2mm wide slot for tightening to the camera and 5.5mm thread above the module to fit into the camera.
The author remixed this model.
