A quick-printing desktop catapult for launching small objects.
This 4-part catapult design uses minimal filament and prints fast. Press the thumb pad to rotate the arm forward until it hits the stop—that's when your projectile launches. Release the button and gravity automatically resets the trigger for the next shot.
Friction posts hold the two halves together with no hardware needed. The entire assembly is just four printed parts that snap together in seconds. Perfect for desktop fun with mini erasers, small balls, or whatever fits in the basket.
