18650 battery-case for two batteries and the possibility to indicate if the batteries are charged or empty with a little two-colored plate on top of the lid.
For the plate, I actually wanted to have two plates with different colors but sadly my printer was not that accurate when printing the plate-compartment. Therefor I made the plate 1,5mm thick, which is enough to get it to stick inside the compartment.
