Matek Optical Flow & Lidar Sensor 3901-L0X Housing (for FPV/INAV Drones)
This is a custom housing designed for the Matek Optical Flow & Lidar Sensor 3901-L0X / PMW3901 module, created to mount securely under The Scout FPV drone (or any similar multirotor build running INAV/Betaflight/Ardupilot with optical flow support).
The housing protects the sensor, ensures alignment of the optical flow camera and LiDAR, and makes installation/removal straightforward with standard hardware.
Features
- Two-part housing design (top & bottom cover) for easy assembly and protection
- Precise cutouts for the optical flow lens, LiDAR emitter/receiver, and wiring clearance
- Low-profile mount to fit neatly under the drone’s frame with minimal airflow disruption
- Countersunk screw holes for a flush, professional finish
- Nut sockets designed for M3 nuts (secured with super glue for extra hold)
Printing
This design has been successfully printed on a Flashforge Adventurer 5M using preset profiles with only minor adjustments.
Tested Filaments:
- PETG-CF (Carbon Fiber Reinforced PETG): Provides rigidity and heat resistance, perfect for drone applications.
- TPU: Flexible and vibration-dampening version for softer landings and additional crash resistance.
Recommended Print Settings:
- Nozzle: 0.6 mm
- Layer Height: 0.2–0.25 mm
- Supports: Tree supports (as needed for overhangs)
- Bed adhesion: Brim recommended
Assembly
- Requires M3 countersink screws and M3 nuts
- Nuts fit into recessed sockets; a small drop of super glue keeps them in place
- Top cover secures with M3 countersink screws for a tight fit
- Tested with both PETG-CF and TPU housings mounted on The Scout drone
Notes
- Designed and test-fitted specifically with the Matek 3901-L0X optical flow/ToF module
- Compatible with other drones where the sensor is mounted under the center frame
- STL files include both top and bottom parts
Durable, lightweight, and field-tested in both carbon-fiber PETG and TPU for flexibility.
