LP-E6 Battery holder

Hi people,

I am building some DSLR equipment for video making and I could not find any of this battery holders around here (the guys from @adafruit sell something but cost 14$...), so I decided to model and print one. I have record the process.
You could find almost everything in the videos and if you have any questions just ask here.

The four hole around are supposed to fit with M3
