Model Rocket Launch Controller

I made a blank lid for the launch controller so people can personalize it. For the final version I created a 12.2mm hole for a toggle switch with safety cover, a 16mm hole for the push button switch (normally on) to launch. Also 5mm holes for the banana plugs going to the alligator clip leads connecting to the rocket. The LED hole is also 5mm.

I reconfigured this and got rid of the screw holes I went with 10mmx2mm magnets printed into the lid and base. Not very sturdy but it's ok.

Here is the tinkercad link to both files. Please make a copy and do not edit the original. It allows you to ungroup all of the objects and make changes.

About the wiring:
Keep in mind that Red in DC is positive!! I forgot this and it took me a while to figure out why things weren't working for me.

I purchased or had lying around the following:
1. Rocker Toggle switch with LED 12V. I believe 20A rating but 15A would be fine as well.
2. Banana Plugs both male and female.
3. Momentary Push button switch
