Description
In short: This object is a highly compact, modern take on the traditional slingshot. It features a 3-part 3D printable design: a main body and a screw-on locking ring system that securely clamps a cut party balloon into place.
Don't let its simple look fool you—this pocket launcher is extremely powerful!
Ammo: For the video demonstration, I used standard air rifle pellets, but you can shoot almost anything with this! It works perfectly with regular marbles, steel balls, airsoft BBs, or even your own 3D-printed projectiles. ⚠️ Just make sure to avoid any sharp objects that could damage or cut the balloon.
Power: As demonstrated in the videos, a single air rifle pellet can easily pierce right through a metal soda can with zero effort. Using a large marble or steel ball delivers an equally massive impact.
⚠️ WARNING – IMPORTANT SAFETY INFO: This is not a simple toy. If you choose to print and use this launcher, you must exercise extreme caution.
Please use this responsibly and always wear eye protection.
⚠️ Important: Make sure the balloon material does not cover the screw threads at all. It must sit completely flat on the rim so the parts can screw together properly.
