Anyone interested in a flare gun build?

Got a project I wanted to finish for the 4th of july but it got canned when I didn't have the skills or cash to do it. I run a small product testing, design, and development company and lets just say my cad skills are tinkercad level even though I must say I do pretty good... if I was in elementary school. I do better in the hands on builds but am working on freecad, blender, and others to see which one I like using best and getting at it. So any fun gun people on here want to design something cool and maybe get it to market?
