Ederdrone
An open, five-inch autonomous quadcopter. I designed the carbon-fibre frame in CAD and I'm sharing the design for free, so anyone can build one.
Design stage: not built or flown yetSmall, stiff, and built to fly itself.
A five-inch class frame: big enough to carry a companion computer and camera, small enough to stay cheap to build and repair.

These are renders of the design, not photos of a finished drone.



The CAD design is free.
Download the frame, print or cut it, change it, build your own. No sign-up and no cost.
- Interactive 3D viewer of every design
- STEP, STL and FreeCAD files for each frame
- Parametric FreeCAD scripts you can re-run
- Free for personal use and learning
Rotate the models in your browser, then download the files from the Scripts and files section.
Where it's at.
- Frame designed in CAD
Carbon-fibre X frame, arms, plates and motor mounts modelled and rendered.
- Software in simulation
The PX4 and ROS 2 stack builds and runs in simulation.
- Publish the CAD files
The designs are up as a free download with a 3D viewer.
- Build the first frame
Cut the carbon, assemble, wire up the flight controller.
- First flight
Manual flight first, then autonomous missions.
