I made it into a night light, and added a base for the power switch and the cord. The power supply, switch and connector, came from an old USB disk drive case.
I hogged out the inside of the rocket, printed a cylinder to stick the LEDs to, and glued it in. There are also a stick-on LED strip around the inside of the nozzel to light the flame. There wasn't enough room to route the wires between the rocket body and the nozzel, so I ran the wires outside and made them look like hoses. It took a while to fish the wires through the smoke.
Also, I used Meshmixer to split the rocket body into 3 parts, so I could print it without supports. It is all PLA and I hope to paint it soon. McMaven.
