It has to be tight fit. Post-Printing You need two pieces of metal, realy thin. Cut two piece of that metal and fit them like in pictures, then solder cables on those. After soldering just clue them in place. I used medium CA. Just make sure that you dont clue the contact surface that hits the pins inside of the camera. And you need to drill hole on the battery hatch. Make sure to adjust the step down to max 4.2v and clue the adjusting screw.
