Aliexpress 320mm wheel button plate

thingiverse

**Disclaimer** Although you are probably able to make a nice button plate like I did. This is not a finished project. There are still some small design flaws and things that I would do differently if I would make a new design. I just shared the design in the hope it would be useful to others. When there are question I will always try to answer them in the comments. But just realize I made this in my free time and shared it with the community as is. The button plate is designed to be compatible with a (specific) 320mm wheel which I bought on Aliexpress. But it might fit other wheels as well of course. I made this design to use the wheel on a ~~Thrustmaster T300 base~~ OSW direct drive base for simracing, but you could probably (with some modifications) use it on another base or even a real car. This thing only includes the button plate itself. To make a fully functional wheel including magnetic paddle shifters and Thrustmaster adapter you need the following things as well: **Magnetic Paddleshift shifters for simracing (logitech)** by [dankart27](https://www.thingiverse.com/dankart27/about) https://www.thingiverse.com/thing:2724966 **Thrustmaster T500, TX, T300 Wheeladapter** by [Slowy](https://www.thingiverse.com/Slowly/about) https://www.thingiverse.com/thing:976223 **Update September 2018** In the meantime I moved from the Trustmaster base to a OSW base. So instead of the Trustmaster adapter I'm using a quick release system now. Furthermore I have added two adapters to create a bit more room between the steering wheel and the button plate, as well as cover the horn. I also bought a new steering wheel with a flat bottom, I can confirm that the button plate also fits this steering wheel. **Update February 2019** I get a lot of question regarding the electronics. As of present I don't have a complete guide on how to do everything. All the available information is the the two included Arduino projects: * For Thrustmaster builds see: t300_f1_wheel_emulator_v1.ino * For USB builds see: hid_joystick_button_plate_v1.zip For the Thrustmaster builds, a good source is http://rr-m.org/blog/. For general USB HID builds the Arduino Joystick library can be really helpfull: https://github.com/MHeironimus/ArduinoJoystickLibrary. There are of course also many tutorial on this library. In a perfect world with infinite amounts of free time I would write a nice how to guide. In reality I'm not sure if this is going to happen anytime soon. **Update June 2019** Upon many request I (tried) to make a wiring scheme for the electronics. Let me know if that helps and if things are unclear or if I made a mistake somewhere. **Update October 2019** I see many people struggling with connecting the SS pin when using an Arduino Pro Micro. I have not tested this myself, but I guess its much easier to use an Arduino Nano when you're not planning on converting your button plate to USB HID later on. **Licence** This work is licenced using the CC Attribution-NonCommercial-ShareAlike 3.0 Unported (CC BY-NC-SA 3.0) licence which restricts commercial use. With the only exception that I gave https://srpsimracing.com.com permission to manufacture and sell the buttonplate to a small group of sim racers. I believe this is not actual commercial use since they only sell to there members with no real profit margin. I just wanted to make this clear since I got some questions regarding this issue.
