Here I will explain to you how to make a DIY Sim Handbrake. This DIY Handbrake is easy to build, has a strong structure, stable and smooth mechanism.
There is almost no difference between the 3D printed version and the metal version (laser cut or CNC). The assembly will be almost the same. You can use this tutorial if you have opted for a steel/aluminium handbrake.
