Thumb Knob and Spring cups for Maker Pro MK1 / Duplicator 9

These work perfect on my Maker Pro. Like A Glove. I made them to fit on the Maker Pro MK1 and Duplicator 9 cause of the spring size and height and width of bed plate.

The bottom cup is the one with the small extrusion on it and it fills the gap from the 5mm hole and 3mm screw.

The top cup on the deep end the ring inside will need popped out as it doesn't fit inside the spring and is only there for support.
