Gimbal Camera Stabilizer with Arm Brace

Turns out that it is not easy to balance a full frame DSLR and lens for cinematography. These things are heavy and holding 2-3kg in one hand is demanding.
I added an arm brace so that the weight is better distributed and the stabilizer can be controlled by the whole arm. You can use the included extensions or a monopod to balance everything. The shown monopod is a Manfrotto 676B but any should do.

The handgrip has an arca style guide so that it can be attached to a tripod for balancing.
All printed in Carbon fiber PETG.

Glue the halves for the weights together and fill with lead shot.
Large will be 500 gram, medium 150 gram and small 100 gram. Balance so that it takes the camera to swing from horizontal to vertical in 2 seconds.
