3MM Easy Snap together Bed Leveling Knob for Malyanm150/Wanhao i3 and Monoprice Select

Just Done a New design for the bed adjustment Knobs, be advise they are 16MM in Dia so they would fit on my Malyan M150,Wanhao i3 and Monoprice Select, 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 with a small pair of pliers, 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 :-)
