Print in place launcher that uses a slip trigger to fire printable ammunition. CAUTION, stay safe, don't aim at people.

The trigger prints in place so no major assembly required, all you have to do is loop the elastic on as shown in the pictures. I recommend printing the “pin” with increased walls and infill density (I used 4 walls and 30% infill. When I initially printed with 2 walls and 15% infill the pin broke from impact at the stopper end).
