Boomerang

<p><em>I think this might be the oldest published 3d printed boomerang. I uploaded it to another 3d sharing platform in 2011.</em></p> <p>A simple tri-blade boomerang.</p> <p>Look anywhere on the web for throwing instructions, e.g.: <a href="http://www.rediboom.com">http://www.rediboom.com</a> - this is an actual returning boomerang!</p> <p>Edit: Videos of this design in flight have been posted on Youtube. Thanks guys!</p> <p>I'll add more once I find them.</p> <p><a href="https://youtu.be/38K8bOXgk2M">https://youtu.be/38K8bOXgk2M</a><br/> <figure class="media"> <oembed url="https://youtu.be/Vd0Mm0uMtkA"></oembed> </figure> </p> <h3>Print instructions</h3><p>The first of these I had printed in ABS; size should fit into a 20x20 cm bounding box, thickness should be 3.5 mm. Making it a little larger won't hurt, but the 3D printing company I used only has a 20x20 printing area.</p> <p>Meanwhile, I have printed plenty of these in PLA, too. Also, different sizes work well, anything between 150 mm and 300 mm squared should be fine.</p>
