Rocket Launch controller box.

This is a box for a launch controller I made.I have uploaded the .stp file so you can easily make modifications for the parts you intend to use.The box can fit a 9v battery, or a 4 AAA battery holder as designed.It uses a push button, a continuity LED, and a safety key.The wiring is simple, but that's beyond the scope of this model.I used a shorted TS 3.5mm mono plug and a matching jack for the safe keyI used a 2 prong extension cord for launch leads, so the case will fit a 2 prong panel out
