My Fully 3D Printed 2-DOF Racing Simulator

For the past 8 months, I’ve been deep into a project designing and building a 2DOF racing simulator that’s almost entirely 3D printed. And now, I’m finally at the point where I can say it’s alive and moving!

Every structural part, mount, and motion element—except for the electronics, screws, nuts, and bearings—has been 3D printed.

I used a combination of PLA and PETG.

Here is the platform (with the first version of the motor) :



Why a 3D Printed Motion Simulator?

There are already many racing sim builds out there, from wood frames to heavy-duty aluminum profiles. But I wanted to push the limits of what 3D printing can do in a mechanical, real-world application. I set a personal goal: make it functional, strong, and modular—without relying on traditional metal fabrication.




The motors are stepper motors connected via motor driver to an Arduino.

Meanwhile I’m testing the 3. Version of the motor. The First 2 versions were with gear ratio of 1:1 but it was a little bit weak so I decided to built a gearbox with 2.5:1 so I have enough power, actually more than needed.

In this video I’m testing the motors. The motors are really low noise motors due to the micro steps function of the driver:

Right now, I’m deep in the testing and fine-tuning phase.

I’m using a variety of racing sims for testing. Assetto Corsa being my go-to for its modding flexibility and realism.

What’s Next?

• Test long-term reliability.
• Build the enclosure.
• Maybe expanding to 3DOF.

I will share the next steps with you.

Thanks
