The Sproinger - Surprise Prank (mk1)
thingiverse
A sproinger is an entertaining gadget that involves a kitchen timer, a spring, and a set of printed parts. Begin by removing the timer mechanism and installing the sproinger components. File any rough edges for a smooth fit if necessary. Set the spring halfway so that it meshes with the spinner, then wind the spinner clockwise to adjust the delay time. Compress the spring fully, rotate the launcher counterclockwise until it reaches the stopper, hide the device along with its ammo, and wait for the surprise!
