3MM Easy Snap together Bed Leveling Knob

Just Done a design for the bed adjustment Knobs, be advise they are 20MM in Dia so they might not fit on every printer, it is a 2 parts system with a hexagon Pocket inside to put the 3MM nut and a easy way to align the 2 parts , just have to snap them together, no glue, no more watching the print as it goes to pause and incorporate the nut in the printing process ... easiest as it goes.. Enjoy :-)
