Kodak Playful camera and battery holder

I needed a holder for a Kodak playful action cam and an extra battery. I'm planning to run a threaded rod in the center hole up to a 3d printed Gimble mounted on a PVC pipe to hold the camera on my Kayak. The battery is a cheap usb charger that you can pickup at Staples, it triples the runtime of the camera (about 3 hours continuous recording).
