Battery Holder for Mophie Duo V1

Here's a first attempt and trial for learning purposes for a holder for the mophie juice pack duo. It's intended to be attached onto a camera or Movi stabiliser using a 1/4 20 bolt and nut. This model worked surprisingly well for a first attempt. I just left a little too much room for the battery not realising the tolerances are very close in the 3D printing.
