Simple Handbrake (Sim racing) modified
I modified the case to fit to desk without any other part.
You can add a piece of rubber on the screw for better grip on the desk.
I also modified the handle, i shortened it.
You can program this with arduino or any other microcontroller
I glued all the piece that need to connect with hot glue
For the lever piece I used 4 perimiters and 50% infill
For the handle I used 3 perimiters and 15% infill
For the case I used 2 perimiters for the 'walls' and 4/5 with 100% infill for the clamp where it fit to the desk
