I have been making videos about working with various small ESP32 IoT circuit boards and it seems handy to have a head mounted camera. Not really into headbands. So a baseball cap mount made the most sense. I an not going to use the waterproof camera case and I wanted the mount just a bit forward on the brim. So I mixed a couple of items from Thingiverse to make a new mashup.
I remixed these:
