Catapult for throwing small balls. The force of the throw is determined by the force of stretching the rubber band. Using the beak, you can secure the catapult, aim it, and then press the button on the beak and shoot. 

You need a rubber band diameter of 60 - 70 mm and an M3 x 6 screw(s).

The individual parts of the catapult can snap together. For better strength, it is advisable to use super glue or screw the individual parts together.

The beak must be held firmly to be able to maintain the force of the catapult, tensioned by the rubber band. Therefore, it needs to be screwed in using an M3 x 6 screw.

The easiest way is to print the first pad, where all the parts are arranged in a row.

If you would like to print individual parts, you need to print: 

  • floor
  • side_1, side_2 
  • axis 2 pieces 
  • partition 
  • wheel 4 pieces 
  • gear wheel 
  • catapult 
  • shooting_place 
  • beak 
  • button 

For assembly see pdf file.
