i have also added a small bridge to protect the flat ribbon for the bed
looking at the machine i think the next will be to add some protection for the endstops...
the x one is direct to the motor and big risk of the wires getting in contact with the motor axle
also the Y endstop is a bit troublesome.... for both endstops the adjuster screw is a pain to get at.
other than that i think the printer is ok as such
