I originally tried to design a pert to go on the top side which would save having to unscrew the bottom plate but felt the simpler and more efficient design was one that fit on the inside. It is simple to remove the screws that hold on the base and using magnets make the addition of the cover very easy.
Did you print and try the part?
Did it work for you?
I have not had any problem with mine and I felt that that the part also provides a little extra protection of the wires from the underside.
