About this 3D model

I haven't tested this yet. Waiting for nozzles to get here to recover from an unfortunate schmelting accident. I'm hoping this will keep my battery snapped into the back of my Disco, so I don't have to use velcro or rubber bands anymore. If this works, let me know, or lt me know what to tweak. I'll post the skp when it's closer to done. Thanks!
