An adapter from the GoPro mount format, having an endpoint with 2 conectors (the internal one) and a tripod screw.
It's intended to be used with devices which have a nut for the tripod screw (which, by the way, it's a ¼ " screw).
There is a recess to insert a washer, to prevent wear on the 3D printed piece.
I made it to be used with my Logi C920 webcamera (in the cover image).
If someone wants to modify the adapter, access the TinkerCAD project I made for it: https://www.tinkercad.com/things/cga8pc1cYBC-gopro-to-camera-tripo-screw
