The STEMFIE Calibration File is a collection of parts demonstrating several types of fasteners, such as fully-threaded and shoulder screws, spring pins, washers, threaded nuts, and cam-locking nuts. This set also includes a couple of tools for holding and driving the fasteners. 

All parts are nested into a single compact build plate measuring 104 x 88 mm, which typically takes three hours to 3D-print, consuming 26 grams of filament.

The STEMFIE Desktop Catapult is perfect for shooting ping-pong balls or crumpled paper. The ball-holding beam moves using the energy stored by two rotor springs. To arm this catapult, you rotate the beam until it locks into place held by the trigger.  You can shoot ping-pong balls into cups or hit and flip the STEMFIE shooting target, which is included in this project.
