3 GoPro battery screw top case +2 MicroSD cards

Remixed from https://www.thingiverse.com/thing:3973487 The original design had a very tight fit for the batteries and cards, as well as no ability to remove a jammed battery without total destruction (had to do that). I have added 3.1mm holes under each battery so you can push out a stuck battery with a reasonably sized tool. I also added a break in the 2 interior walls to allow flexing as the material and batteries may grow and shrink do to temperature changes. I scaled up the whole design ever so slightly to address the overall fit issues with cards and batteries. I recommend printing at 10% or less infill just incase you have to go nuclear on the case to recover your batteries... at 10% it was quite the chore so I have no doubts this will handle a LOT of abuse being 90% hollow.
