100% 3D printed Catapult prank. Print in either ABS or PLA. The Catapult can either be attached to the computer monitor with duct tape or foam tape. I used foam tape because it conforms to the monitor housing better. Use light weight fishing string the connect the trigger to the mouse or keyboard cable. All of the parts can either be assembled with glue, solvent weld, or heat the plugs down to the top surface.
