Lightweight Micro Drone Frame (Coreless Motor Compatible)

This is a compact and lightweight quadcopter frame designed specifically for 8.5 × 20 mm coreless motors, making it ideal for micro drone builds, beginner projects, and experimental setups.

The frame has an overall dimension of 110 mm × 110 mm, providing a balanced geometry for stable flight while keeping the structure minimal and efficient. The design focuses on weight reduction without compromising rigidity, featuring reinforced arms and a central mounting platform.

When printed using PLA with 20% infill, the total frame weight is approximately 18 grams, making it suitable for low-power propulsion systems and extended flight time.

Key Features:

• Designed for 8.5 × 20 mm coreless motors
• Compact 110 × 110 mm footprint
• Lightweight structure (~18 g with PLA, 20% infill)
• Reinforced arms for improved durability
• Central mounting area for electronics and battery
• Simple geometry for easy 3D printing (no supports required in most cases)

Printing Recommendations:

• Material: PLA (recommended for weight and ease of printing)
• Infill: 20% (adjustable depending on strength requirements)
• Layer height: 0.2 mm
• Supports: Not required
• Orientation: Print flat on bed

This frame is ideal for hobbyists looking to build a small, efficient quadcopter or experiment with custom flight controllers and lightweight payloads.
