LEGO Like - Power Functions Battery Boxes

Made this LEGO style battery box and top a while ago, and forgot to upload it. There are a few different sizes. Also there is a version of a PF style connector that you can use (4) SIP's as the pins. The tops need 1/2 of a PF extension cable. I know it is a LEGO sin to modify pieces...but....I have a 3yr old son who is like a LEGO godzilla.

Once cut, the PF socket will fit snugly into the opening on the top piece. Fish the cable thru from the underside. The bend on the cable looks bad,
