GoPro battery storage box

This is a box designed to hold GoPro Hero 4 batteries. More details can be found on my blog at http://www.revelut.ch/2016/07/11/box-for-gopro-batteries/
The design is done using fusion 360 and can be fetched at http://a360.co/29ItWzl
This is supposed to be laser-cut out of 3mm mdf.
Files exported from Fusion 360 (dxf) can also be found on my git repository : https://bitbucket.org/Bruce314/lasercutdesign

Assembled using wood glue and 2 M3x12 screws and bolts
