Boomerang Hand Axe, Double-Edged Axe, Boomerang

Print settings: 0.2mm layer height, 20% spiral infill, 5 vertical perimeters, 4 top and bottom layers. Throwing method (for right-handed individuals):

1. Find out where the wind is coming from.

2. Directly face the wind.

3. Turn 45–90 degrees to the right (if you are left-handed, you must use a left-handed boomerang and turn to the left).

4. Hold the boomerang at eye level, perhaps slightly higher.

5. Tilt the boomerang slightly (about 5–10 degrees).

6. When throwing, aim roughly at the horizon, maintaining a 5–10 degree tilt, and make sure to give it enough spin!

These are just general throwing guidelines! Specific techniques may vary depending on the model and weather conditions. Additionally, I must warn that boomerangs can be dangerous, so you should ensure no one is in its path. It's important to remember that boomerangs were originally hunting weapons. I also recommend printing in a signal color for easier visibility.
