Battery Double Case, Pocket-Friendly

If you need to carry a few batteries in your pocket, bag or suitcase, this battery holder is for you.

It holds two standard batteries and has a carry-anywhere design.
At the same time, it has rounded edges and a shape that allows it to fit in a pocket without getting in the way.

The batteries each have their own chamber and this protects against short circuits, leakage and damage between the batteries during transport.
Should an overpressure occur in a battery, the lid itself can open safely and release the pressure.

There are currently models for the battery size: AAA, AA and 18650, but should you need a different size, let me know in the comments (cylinder batteries only).

Printing notes:
For each type of battery there is a complete model with lid + bottom, and a model for each part separately.

Can be printed in many materials, but I have tested with PLA and PETG.
(Be aware that PLA usually has a low melting temperature and this can cause problems in a hot car or in the sun)

Depending on the used filament and printer calibration, the lid can be loose or tight - scaling the lid a tiny bid will compensate far that and give a good fit.
