Complete Pedal for X-sim simulator

Hello, I am developing a complete simulation system based on arduino leonardo and arduino uno, the system will have pedals, steering wheel with encoder and force feedback, handbrake, shift lever H with 6 and 12 speeds, in the end it will be developed a 3DOF system, but to be able to finish those projects which I have in 20% each, except the pedals that I only need to finish the clutch and the spring system with suspension layers to support more than 20kg of pressure,

I created a small patreon because since I am an independent university student, I have to work full time in my free time to pay my tuition and my personal expenses, as well as being able to repair my 3d printer that develops based on electronic waste, and buy more filament as materials for the projects, in the patreon the projects are specified and as I hope to be able to advance, I hope I can count on you
