Rush hour rules are easy. Clear the way for the red car to be able to leave the parking lot. Cars can move only forward/backward, no lifting the cars!&nbsp;Printing:<ul><li>Depending on the challenge difficulty, you'll need to print up to 4 trucks and 12 small cars. One of the small cars (preferably convertible one) must be printed in red.</li><li>Parking lot can be printed using different colors to highlight lanes and arrows:<ul><li>Option A - use filament color change in a layer. From 0 to 3.8 mm white color, from 4 all the way to the top grey color.</li><li>Option B - use provided 3mf file and AMS.</li></ul></li><li>Asphalt is as separated model for better visual.</li><li>0.2 mm layer height.</li><li>No supports needed.</li></ul>Other hardware and assembly:<ul><li>Besides filament, you'll also need 72 pcs of cylindrical neodymium magnets 5x1 mm (diameter x height). It is not mandatory, but it's much more comfortable to play with magnetic cars. Use superglue to attach magnets to place.</li><li>New travel friendly design - lid now serves as a stand too and is held in place (in both closed and opened state) using 8 pcs of 8x3 neodymium magnets.</li><li>Pieces of filament to connect hinges with lid and parking lot.</li></ul>You can generate challenges using online generator, for example <a target="_blank" href="https://www.thinkfun.com/internal/rush-hour-challenge-generator/" rel="nofollow noopener">here</a>. I attached several example challenges.

This is the STEMFIE Quick-print Sample file. It is an easy way to test a few STEMFIE parts and fasteners. The print typically takes 40 minutes, consuming roughly two meters (6 grams) of filament. You can also check the <a target="_blank" href="https://stemfie.org/scf" rel="nofollow noopener">STEMFIE Calibration File</a> for more elaborate types of fasteners.

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 this <a target="_blank" href="https://makerworld.com/en/u/2144800777/collections/13181" rel="nofollow noopener">project</a> includes.<ul><li>Assembly instructions: <a target="_blank" href="https://stemfie.org/sps-000003" rel="nofollow noopener">stemfie.org/sps-000003</a></li><li>Assembly video: <a target="_blank" href="https://youtu.be/8AIVcwuRmV4" rel="nofollow noopener">youtu.be/8AIVcwuRmV4</a></li><li>STEMFIE news 👉 <a target="_blank" href="https://x.com/stemfie3d" rel="nofollow noopener">X.com/stemfie3d</a></li></ul><figure class="media"><div data-oembed-url="https://youtu.be/8AIVcwuRmV4"><div style="position: relative; padding-bottom: 100%; height: 0; padding-bottom: 56.2493%;"><iframe src="https://www.youtube.com/embed/8AIVcwuRmV4" style="position: absolute; width: 100%; height: 100%; top: 0; left: 0;" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen=""></iframe></div></div></figure>
