The free 3D-printable educational construction-set toy you can download and make at home!

Here is another STEMFIE catapult project with fewer parts and, therefore, it will print in just a few hours. You can press and hold the catapult's base on a tabletop and shoot the ping-pong ball by quickly pushing down the beam.
