Hộp đựng pin và sạc Canon

This box easily stores 4 Canon Batteries, as well as their charger (with one additional battery inside it).
It also has place for velcro cableties to attach the chargers cable to it.

Original batteries and the charger fit snugly. The cable can be attached without removing the charger from the box. (Please check the temperature if you are charging your batteries with the charger inside the case!) 

I'd like you to keep the watermark in, as it is not really visible, but if you really don't like it, for personal use you can just render the provided OpenSCAD model for yourself.
