A blow dart toy that can fly ten meters, only needing a straw and a toothpick

This is a 3D printed fletching assembly designed for DIY blow dart projects, to be used with common thick straws and bamboo skewers/toothpicks for assembly and testing.

This fletching features an aerodynamically optimized design, improving the stability of the dart during flight through a reasonable fin layout and structural proportions. The fin structure helps the dart maintain its attitude, reduces yaw during flight, and results in a smoother overall trajectory.

Design Features:

⭐Aerodynamic Fin Structure: Optimized fin shape and layout to provide stability during flight.
⭐Lightweight Design: Reduces the impact of tail weight on the overall center of gravity, maintaining good weight distribution.
⭐Highly Stable Structure: Combines fluid mechanics and structural mechanics design principles, reducing material usage while ensuring strength.
⭐Easy to Print and Assemble: No complex processing required, suitable for 3D printing enthusiasts for DIY production and structural testing.
⭐Recommended Printing with Flexible TPU Material: TPU has good elasticity and impact resistance, making it more suitable for the actual use environment of the fletching assembly.

Printing Suggestions:

* Material: TPU (flexible filament recommended) ⭐⭐⭐ (Be sure to dry the filament first!!!)
* Infill: Adjust as appropriate based on printer performance
* no supports (minor adjustments may be needed based on print orientation)
* After printing, it can be assembled with a dart shaft component of the appropriate size
