This is an adaptor that connects to the common 1/4" thread found on action cameras (Gopro / SJCAM etc) and fits into the Wyze camera mount for the prusa mini featured below.

This can also be used as a free standing camera mount.
I printed this in Prusament PLA and it's working fine but PETG would probably give a more durable part.
Printed using the standard Prusa mini and Prusament profiles with infill at 5% but added a modifier on the threaded part and set infill to 25% there and speeds of 20, 45, and 25 for External perimeters, infill, and perimeters.
The author remixed this model.
