9Volt Battery box

I designed this 9 volt battery box to go inside my son's R/C car that is used to power auxiliary LED lights. There are two versions one with a cut out for the power lead in the front and the other has a cutout on the side both versions have lids. I figured the box might come in hand for other general/hobby things that you might want to keep a battery a little bit more out of the environment etc.This is my first design so let me know if you have any suggestions or questions.
