I'm currently taking a 3d printing class, and we get to design and print something as part of the class, so I designed this 3d gimbal that will be the control handle for the steadicam.  My goal is to print it all as a single unit, and then you snap away the supports to get it to move.  I'm still working on exactly how the pieces are going to be printed, but have the gimbal functionally designed.

The blue in the picture below is an ordinary skate bearing.  I'm using some Bones Reds because they are pretty cheap and have really good reviews on amazon.
