This is a concept of a printable 2-Axis-GoPro-Mount. It can rotate 360° horizontal and about 20-30° vertical. It is meant to be built in the deck of a unmanned boat, so that the upper glasplate is on the same level as the deck is. Print and assemble.You will need 2 Servos, one Standard-Size and one Micro-Servo. The Micro-Servo is for the vertical axis, the standard-servo is for the horizontal axis.You also need a small mirror and some tubing with threads on the inside and 12 screws that fit in the tubing. Also you'll need some stable steel wire, as bowden cable for the vertical axis. You can see that the rod in the middle needs to be sliced open, to allow for the bowden-cable to go through. I have designed this thing roughly about a year ago, but I havent printed this part yet, due to a misconfigured printer, but I have a GoPro now.
