TkkrSpring springy thing
prusaprinters
<p>This is the winning entry of the TkkrLab maker 3d print <a href="https://tkkrlab.nl/cybersaturdays/2021_07_17_3d_print_wedstrijd/">contest</a> on July 17, 2021. The goal was to design and 3d print an object which jumps in the air as high as possible; the energy storage element (spring) must be part of the object (i.e. no catapult). This entry can jump approx. 1.2 m in height.</p><p>Any layer height is fine. I used Fillamentum PLA (Noble Blue). Other brands of PLA should be fine as long as it is not too brittle. PETG might be better but I did not test that.</p><p>Store the model in unlocked state, otherwise the spring loses its springiness over time.</p><p><a href="https://youtu.be/kTw3aQFFd6E">Video</a> of the jumping action!</p>
