Cinebox

A 3D-printed V-mount power box for the Canon R5C, built to bolt onto the SmallRig cage.

The Canon R5C is a cinema camera that runs out of power fast. Cinebox puts a V-mount battery on the back of the rig and turns it into a power hub, with four D-Tap outputs for monitors, wireless video and lights, all switched from one guarded master switch.

It's printed in carbon-fiber nylon with brass inserts, so it holds up to real use, and it bolts straight onto SmallRig's 3890 cage.

Each one is printed and built when you order it, so it ships in 3 to 6 weeks, with free US shipping. It's a one-time run while supplies last. If you have your own printer, you can buy the file for $25 and print it yourself.

Versions for two more SmallRig cages are on the way.
