Nerf RapidStrike Battery mod

My initial plan was to replace the standard battery box with something that can hold a 6-cell 7.2V NiMH/NiCd battery pack commonly used in RC cars, but it was too short.

I remodelled intofocus's box (which I really liked because of the way the connector is made) to incorporate the front lid (I removed the bottom screw-hole for easier printing and it does not really need the 3rd screw), still I had a hard time fitting the NiMH pack into the box (it was the Tamiya connector giving me problems)
