Waterproof Battery Box for 2 AA batteries

Battery box I created for my RC catamaran. I store the batteries in the bilge and they sometimes get wet.

I created this design using TinkerCad. You can modify the version 2 at https://tinkercad.com/things/cZ0HxKZN9fo and version 4 at https://tinkercad.com/things/14Qw063qCVm.

Version 4 has a longer battery tube to allow for larger springs and a glue on bottom plate. It also has much thiner walls making it print faster, use less plastic, and fit in smaller spaces.

I recommend version 4.
