About this 3D model

I decided to have a go at designing something 3D. This is a case for a simple 9v flashlight that uses a 9v battery, two 5mm LED's, a resistor, and a switch. It uses a snap joint to join the two parts. I\'m not good with blender at all so I did it with Autodesk Inventor. You\'ll probably have to play with the orientation and stuff so that it will be printable. --EDIT-- I removed the snap joint because I found it wasn't very printable (at least the way I had it) so the top just fits quite snugly on the bottom.
