This is a pistol grip for Olympus Air a01 lens-style camera. The idea behind it was to design a handy grip to make the use of the camera with long and heavy lenses easier. Also, I wanted to keep the ability to mount phone on the back side of the camera. So, I've designed this nice grip (obviously, inspired by Glock 19 handgun).
The camera is mount on the grip via standard tripod screw, that is glued with superglue to the extension pin, so it can be screwed from the bottom of the grip.
Later, I've found out that the grip perfectly fits Sony AS15 and Sony AS20 action cams (in waterproof enclosures) and furthermore, the grip is completely watertight and very lite, so it holds camera afloat nicely!
Grip itself was printed standing on flat bottom surface, no raft/brim/supports needed. The screw pin was printed upside down with brim. The camera mount screw was glued on the top of the pin afterwards.
Please, comment if you want me to post step-by-step creating process overview.
