The Sim Racing DIY Button Plate building kit has been designed to be easy to build without expensive tools or advanced knowledge! You can modify the front plate as you wish (add buttons, a screen, LEDs, etc.) and cover it with carbon. You can also mount the wheel of your choice. This DIY Sim Steering Wheel can be built with a small budget, depending on the parameters you have chosen (Choice of material, USB Board…) and the equipment you have (3D Printer).
