Hand Copter (Parametric)

The Hand Copter, called 竹とんぼ or Taketonbo - bamboo dragonfly a Japanese toy made traditionally from bamboo. But we have 3d printers now and we can print the blades in our own custom design to perform as we wish.Prints fast and easy. No need for supports! Customizable with parametric values. Make your own and see which ones fly the best!Make sure to use PETG and print slow since the blade is thin (the included stl is only 0.6mm single wall)I used a 3mm diameter x 150 mm long bamboo skewer as shaft. After assembling, make sure to cut off the sharp tip of the skewer for safety. Boost MeBoost me if you like it!
