FPV drone 5inch | Modular Precision Frame System

🚁 FPV_drone_5inch — Modular Precision Frame System (V1.0.4)

Engineered for precision and strength, this 5-inch FPV drone frame is designed as a high-durability 3D printable chassis optimized for prototyping, customization, and modular builds. Whether you are testing new geometry or building custom engineering parts, this layout offers robust geometry, clean internal cutouts for stack mounting, and secure arm rigidity.

🚨 Update Notice: This version features an upgraded, reinforced arm geometry for better crash survivability and a completely redesigned top camera cage to provide tighter hardware tolerances and improved tilt-locking for digital FPV cameras.

⚙️ Design Specifications & Features

- Form Factor: Standard 5-inch FPV Quadcopter layout (True-X). - Electronics Compatibility: 30.5x30.5mm FC stack and 25.5x25.5mm VTX mounting (Optimized for DJI O3, Walksnail, Caddx). - Modular Assembly: - 1x Heavy-Duty Unified Bottom Frame Plate (Grey) - 1x Top Camera Cage / Electronics Shield (Grey) - 1x Rear Stack Guard (Grey) - 6x Precision Cylindrical Standoffs (Orange/Gold) - Precision CAD: Optimized hole spacing for standard FPV electronics, flight controllers, and motor mounts. - Tested Printer: Optimized for print beds starting at 220 × 220 mm (Tested on Creality Ender 3 V3 SE & Bambu Lab A1). - 🖨️ Recommended Print Settings

- Material: Tough PLA, PETG, or Carbon Fiber PLA (for maximum stiffness). Note: Do not use PPA/Nylon unless using an actively heated chamber. - Layer Height: 0.20 mm (Standard / Quality). - Infill: 30%–50% (Gyroid or Grid for structural rigidity). - Walls/Perimeters: 4–5 Wall Loops (Crucial for arm durability). - Top/Bottom Layers: 4 Layers. - Supports: Tree Supports recommended ONLY for overhangs in camera cage mounts. ⚠️ Note on Project Status & Support This model is currently in its 3D Printed Prototyping Phase. Due to current budget constraints, I have printed and physically validated the structural frame fit, but I haven't fully assembled a Ready-To-Fly (RTF) electronics stack yet. If you have the components and funds, you can build a complete, fully functional FPV drone using this frame!
