Boomerang

thingiverse

A self-designed wooden boomerang serves as my inspiration for this model, which features sharper airfoils and measures 20 x 20 units in its STL file. This size conveniently scales to the 3D printing company's offered 20cm x 20cm space. Left-handed users require a mirrored version, included in the downloadable files. For optimal performance, scale between 20 x 20 and 30 x 30 centimeters with a thickness of approximately 3.5 to 4.5 millimeters. My boomerang has a wingspan of 215 mm and is 3.5 mm thick. Enhance wind stability, spin retention, and distance by taping a small weight (coins or washers) to the first arm as shown in the photo. To avoid issues with warping and bending, flatten your boomerang using a hairdryer or heat gun, followed by clamping it to a flat surface. Be cautious of downward-warped wings, as this can cause the boomerang to fly too low. Tutorials on correcting such issues and general tuning instructions can be found on various boomerang sellers' websites, including Ted Bailey's: https://www
