Sim Racing Paddle Shifter

I am uploading my fairly basic sim racing paddle shifter design. Along with .stl files, I am including a .step file for the shifter so you can customize or upgrade as necessary. I used paddles from the following link so I will not upload them here as well. https://www.thingiverse.com/thing:2745297

For each pair of shifter, you will need:

2x 3d printed shifter body

2x 3d printed shifter shaft

2x paddles of your choosing with m3 mounting holes spaced 10mm apart

2x switch (I use the following but you can modify the .step to fit a cheaper microswitch, if desired)
