Shifter & buttons for simulator - wireless/wired

This is a paddle shifter system for 280 mm and larger diameter steering wheels with 70 mm bolt mounting pattern. This design can be built with only shifters or shifters + buttons, wired or wireless via BT.

The complete shifter consists of two shifter assemblies and a base plate. The shifter unit and paddle hinge should be 3D printed. Paddle and steering wheel mount plate can be printed, but I recommend laser cutting or CNC milling for maximum rigidity.

The shifter has a nice and well defined click. It is magnetically returned, and it uses a micro switch. It mounts to the back side of any steering wheel with standard 70 mm bolt pattern.
