Boomerang

prusaprinters

<p>A boomerang that I modeled after one that I made from wood.</p> <p>This is similar to thing:28603, it only has sharper airfoils and I took care that it is about 20 x 20 units in the STL file, which scales easily to the 20cm x 20cm space that the 3D printing company I use offers.</p> <p><strong>Note for Lefties:</strong> You'll need a mirror image of the boomerang. A mirrored copy is included in the downloadable files.</p> <h3>Print instructions</h3><p>Will work best if scaled to between 20 x 20 and 30 x 30 centimeters and a thickness of about 3.5 to 4.5 millimeters.</p> <p>Mine has a wingspan of 215 mm and is 3.5 mm thick.</p> <p>You can greatly enhance wind stability, spin retention, and distance by taping a small weight (coins or washers will work well) to the first arm as shown in the photo.</p> <p>Boomerangs are quite finicky regarding warping and bending. If your boomerang is not perfectly flat, try to flatten it by heating with a hairdryer or heat gun, and then clamping it to a flat surface.</p> <p>The most common issue I have seen is that the wings warp downward when the boomerang cools down. This will make it fly too low, so it should be corrected.</p> <p>Full tuning instructions can be found on every boomerang seller's web site.
