The design of the base plate contains some enhancements:
To assemble the base plate you have to use a longer screw. The orginal screw is a fine pitch thread screw. I havent found a suitable screw to buy, so I have replaced the square nut by a self-made nut which allows me to use a metric screw M5x20 and a suitable washer.
