This is a flash paper based fireball shooter for theatrical effects. these are the 3d printed parts, additional parts are needed, see instructions for details.
In addition to the 3d printed parts, you will need:
â¢ 3" length of 10mm diameter tubing
â¢ 1.5volt GLo plug
â¢ 1/4" nut (or what ever fits your glo-plug)
â¢ Red Round Momentary Push Button Switch
â¢ 1 x 1.5V AAA Battery Case Holder Case Black
â¢ ELectrical Tape
â¢ Alligator Clip
Essentially, this follows the finely detailed project over at Make:Magazine. SO please see those instructions for the process of soldering. What makes this different is using 3d printed pieces to hold it all together. The main piece (titled fireball shooter.stl) is made to hold the tubing and the switch. The hexagonal hole holds the nut for the switch captive so you can secure the switch. The cap piece is meant to cover up the leads on the switch.
Use a little hot glue to hold the tubing in place, and the battery holder to the printed part. And use the electrical tape to tidy up the wires.
