About this 3D model

Modeled from scratch in OpenSCAD from http://www.thingiverse.com/thing:35515 with a couple of minor improvements, primarily being that it is now entirely parametric. I also added channels in the side because I wanted to have the leads come out of the same end of the battery. I have personally tested this with AA, AAAA and 18650 cells but I left the code as open as possible to use any size you need. Feel free to post useful or tested measurements in the comments.
