Sony action cams dont have standard 1/4-20 mount to mount the camera to anything interesting. They want us to use the casing, but that kinda stupid, because you cant add external power supply or external microphone. So I made this to be used for time lapse and other activities. I used this on AS-15, but AS-10 or newer once will work just fine, like AS-30. Simple, glue front cover, back cover and base adapter to the mnt plate. Use good glue, like epoxy or gorilla glue. If you make it out of ABS, feel free to use acetone with some ABS waste to make your glue. Slide 1/4-20 nut into the base adapter. If your mount has too shallow of a screw (hats what she said). May need to file the bottom of the base adapter to clear.
