Project Overview

This EHANG 184 drone model, inspired by EHANG, a leader in autonomous aerial vehicles, is a highly detailed, modular, and fully customizable 3D CAD project. I designed this drone entirely from scratch, without any blueprints, relying solely on observation, research, and CAD skills to recreate every component accurately. Every part—from propellers and motors to cockpit details and landing gears—is editable, allowing intermediate and advanced users to modify, thicken, or redesign parts for their own builds. The main chassis is intentionally left unthickened, and locking mechanisms are omitted, giving users complete freedom to experiment and innovate.

Acknowledgment: This project is inspired by and based on the EHANG 184, a pioneering autonomous aerial vehicle developed by EHANG, a leading company in passenger drones and urban air mobility solutions. Full credit goes to EHANG for the original design concept; this 3D model is intended solely for educational, experimental, and non-commercial purposes.

Important Note: The main chassis has been intentionally left unthickened, and locking mechanisms have not been designed. This allows users the flexibility to modify, reinforce, or adapt the drone to their specific needs. Beginners and intermediate users are encouraged to explore, iterate, and apply their own design improvements. To help with this, I have provided accompanying YouTube tutorials sharing the tips, tricks, and techniques used to design this drone in Fusion 360.

Tips on the Assembly with Supported Screenshots

Although, i recommend everyone to download the full assembly STEP file i have uploaded but let me show you few tips on how to assemble the project with some few screenshots so you fully understand the assembly process please. Let us begin with the base mount (the suspension part). Below is the image of it please

Let us break the first image (screenshot) into the following:

. The Base Mount Assembly (the suspension) is splitted into 2 parts - the right side which contains the right-side landing gear and the right-side arms (both the front arm and the rear arm). The left side which also contains the left - side landing gear and the left - side arms (both the front arm and the rear arm). So, the two are combined with some structures overlapping them in the middle. Look at the image carefully, and you would see those structures that i am talking about please. They are deep black in color with some mounting holes in them.

. Landing Gears and Base Mount (suspension) Assembly

If you look critically at the second image (the screenshot), you will realize that the landing gears are just mounted to the base mount with some grey color structures all the way from the end of each landing gear to the respective base mount. Very clear! Those grey color structures supporting the landing gears to the base mounts have each of them 4 mounting holes, where they are mounted to their respective landing gear.

. The Base Mount and the Main Chassis Assembly

If you look at the first image (the screenshot), you will see some V-shaped mounting structures also grey in color mounted to the respective base mount. Isn't it? Those structures mount the main chassis onto the base mount (the suspension). You secure them with screws.

Tip: Mount the main chassis to the base mount by inserting each of the base mount (left and right-side base mount) into the holes in the main chassis. Look at the image of the main chassis and the holes that i am talking about below please.

In all, we have 10 rectangular holes with 5 holes on each side of the chassis please. Let us also see the image after mounting the main chassis onto the base mount (the suspension). Below is the screenshot please.

Same technique applies to the booth. Having talked about these, a quick one on the arm and the base mount assembly.

The Drone's Arms and the Base Mount Assembly

See the below screenshot showing where to mount the right rear arm to the base mount (the suspension) please. Because they say ''seeing is believing''.

So, all that you have to do is to mount the arm to the base with screws as you can see the 2 screws holes, right? Same thing applies to all the remaining arms please. Very simple! So, for now we at least know a bit about the assembly. Isn't it? Now, let me show you a bit of the interior of the drone.

Can you see a seat module, belt molding, and so on? Yes! To be honest with you, every part in this project is easy customizable ok. So, go ahead and customize them to suit your needs Have a look at how i designed the booth as well. Below is the image please

Looks pretty nice, right? Look at the cabin (the interior cabin) as well. Below is the screenshot.

Section it according to how you want to section it and design your lockings and apply your thickness. Simple as A, B, C.

Conclusion

In conclusion, all these screenshots above will go a long way to actually guide you through the assembly stage, saving you months of hard work, and also show PCBWAY Judges what we called ''design originality''

This project is intended as a flexible, educational platform:

. Intermediate & Advanced Users: Explore CAD modeling, modify structural components, and create your own unique version of the EHANG 184 drone.

. Beginners: Follow the above YouTube tutorials where I demonstrated design techniques, modeling tips, and shortcuts used in this project to help you understand the modeling workflow and start customizing safely.

Most parts were thickened and optimized for 3D printing, while some - such as the main chassis and locking joints - were intentionally left unthickened to allow easy customization for different print materials or assembly preferences.

This ensures flexibility for anyone who wants to build, modify, or integrate their own mechanical components.

  Design Intent

The purpose of this design is to showcase the power of Fusion 360 for precise mechanical geometry, functional details, and creative design presentation.

Although this current version focuses on the mechanical structure only, it is fully ready for the addition of electronics such as:

. Pixhawk 6X or similar flight controller,

. Motors, ESCs, and propellers,

. Lighting and sensor systems.

These will be added in future updates to complete the working version.

 Tools Used

. Autodesk Fusion 360 - for 3D modeling, visualization, and rendering.
