Snaptain drone second battery holder (sits behind controller, completely removable)

You can carry a second battery for your Snaptain drone in this simple pouch. It makes use of the bottom screw holes: without modifying anything, you can jam the two prongs inside the screw holes and it'll sit flush against your controller, without interfering with your grip. If printed correctly, the press fit will also allow for a snug and firm hold, so it'll never fall out.

Bonus point: your controller can now stand up too.
