Here is another STEMFIE catapult project with fewer parts; 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.

The STEMFIE Quick-print Sample file is an easy way to test a few STEMFIE parts and fasteners. You can also check the STEMFIE Calibration File for more elaborate types of fasteners.
Check out the STEMFIE web app prototype to browse, view, and download parts (Github).
