About this 3D model
The screw used to adjust the Z-axis endstop is (according to the K8200 construction manual) installed upside down. That means the screw head is located (when Z-axis is homed) directly on the Z endstop switch. This is very inconvenient when you want to adjust the Z-axis. I simply installed the screw the other way around, making Z-axis adjustment an easy task.
