For anyone that’s new to camera rigs i’ll give you a short introduction here. The most common systems use 15mm Diameter rods (aluminium or carbon fiber usually) that are offset by 60mm (center to center).

The idea of a camera rig is to incorporate manually operated focus systems, as well as enabling one or more two persons to operate the camera easily. For low budget film and documentary use it’s common to use a shoulder rig that’s lets one operator rest the camera (and audio recording, light, batteries and more) on this shoulder and arms.

When combining this with what’s called a follow-focus system (A knob that you twist to smoothly change focus, instead of turning the lens built-in focus ring). Given all the tools to the camera operator enables you to do more with a smaller team (or alone).

All of this gear is usually very expensive and my goal was to create a system that could be printed for under $100, to be open source, and to work with existing parts while being strong enough to handle a DSLR-camera.
