Sony RX-100 battery box

Battery box for two NP-BX1 batteries used for the Sony RX-100 series.
Added a small detail on top part for better lock when assembled.

I limited the direction of batteries in the base by reducing the geometry a bit. They can only be placed with contacts upwards.

Update 23/7-2017:
I bought some new batteries and there is some size variation between original and non-original. Recommendation is to print the parts at 105-110% to accommodate for this variation.
