Button box for SimRacing on PC

Button Box for Sim Racing – Unique 3D Project (STL File)

I am providing the 3D file for my button box, completely designed from scratch, conceived for sim racing and entirely made through 3D printing. It is not a copy: the design is original and unique.

The button box is designed to be assembled with easily available components (mainly from eBay or Aliexpress if you have patience – you will find dedicated links), and it is perfect for those who want to build a customized peripheral for their setup.

🔧 Main Features:

• Completely 3D printable structure
• Dedicated internal housing for Arduino Leonardo (not included)
• Perfectly compatible with PC
• Ergonomic and compact layout

🎮 Required Materials - not included:

• 3 ON/OFF toggle switches ( https://www.ebay.it/itm/187511861952 )
• 3 rotary encoders (ideal for TCS, ABS, engine maps, etc.) ( https://www.ebay.it/itm/187511942608 )
• 5 illuminated ON/OFF buttons ( https://www.ebay.it/itm/187512036856 )
• 1 gamepad-style analog joystick (PS5 controller type), usable as a mouse ( https://www.ebay.it/itm/187512007599 )
• 1 Arduino Leonardo ( https://short.do/vQi2x5 )
• 4 M4 threaded inserts
• 4 M4x20 countersunk screws

⚙️ Operation:

The button box works via Arduino Leonardo (not included).
It is sufficient to configure it to be recognized as a keyboard by the PC:
each button or control can be associated with a key (letters or numbers).

In this way, in racing simulators, you can:

• activate functions such as windshield wipers, lights, pit limiter, etc.
• adjust parameters such as TCS or ABS
• fully manage the game without using the keyboard

📌 Important notes:

• Attached you will find images of how I wired the button box and what keys I assigned to it.

  Of course, that is my configuration, you could decide to set it to your liking.

• As for Arduino programming, it is not very complex; numerous easy-to-follow guides are available online. The important thing is to understand the logic of the keyboard emulator. Each switch or rotary encoder on the button box must emulate a letter or a number on the keyboard.

  Then, in-game, you should assign, for example, the letter A to the windshield wipers, and when you press the button to which you assigned the letter A via Arduino, the windshield wipers will activate.

• Attached you will find a PDF with stickers that you can print to customize the graphics of your controls

Perfect for sim racing enthusiasts, makers, and anyone who wants a personalized and professional setup 🚗💨
