About this 3D model

It seems like every time I build an electronic kit I start by salvaging/cannibalizing a battery housing from a previous project. So I thought I'd make my own design so I could just print them out when I want one. However, I'm not very happy with the result. I started it with the best intentions but as I was finishing it I realized that it was WAY to complex. A much simpler model would work just as well, probably print faster and be easier to modify. So I'm really posting this up with a request: Somebody please make a better one! I'll make a new version and post it up here when it's finished but I cant be the only person who uses these things...
