2-Inch "Unbreakable" FPV Drone Frame (TPU for AMS Optimized)

Tired of snapping carbon fiber arms or cracking rigid plastic frames during basement laps or sidewalk proximity flying? This 2-inch micro frame is designed specifically for durability and flexibility, utilizing the unique properties of TPU to create a "bounce-back" flight experience.

Key Features

• True Unbreakable Design: Unlike traditional frames, this design uses a flexible geometry that absorbs high-speed impacts, making it perfect for beginners or aggressive indoor racing.

• Bambu Lab AMS Ready: Optimized for multi-material or multi-color prints, allowing you to easily customize your look or add high-visibility accents.

• Ultra-Lightweight: Designed to maintain a high power-to-weight ratio for 2-inch props.

• Camera compatibility: 

  • Runcam nano 3: yes

  • DJI O4 lite: coming soon

Optimized Print Settings

To achieve the intended "unbreakable" strength while keeping the frame stiff enough for flight controller PIDs to handle, please use the following specifications:

• Material: TPU (for AMS 68D recommended for the best balance of stiffness and durability).

• Nozzle Size: 0.4mm.

• Wall Count: 2 Layers (Critical for achieving the specific flex-resonance intended for this design).

• Infill: 100% (Solid) to ensure structural integrity around motor mounts.

• Supports: yes

Why TPU?

While most frames rely on rigidity, this design embraces impact displacement. By using only 2 wall loops, the frame remains lightweight and easy for motors to "drive" through the air, but provides enough give to protect your expensive electronics and motors during a crash.

Note: For best results, ensure your TPU is dry. Wet filament can lead to stringing that might interfere with motor bell clearance!
