Elegoo Mars replacement flatcap platform knob

I found a post in the elegoo mars forum;

and decided to try to change the maximum Z-height on my Elegoo Mars printer - and I did!
Maximum print height went up from 155 mm to almost 170 mm. It wasnt very hard, but be careful when changing parameters in your printer. (follow the link to learn how)

I later realized that when my printer was done, it went all the way up and lifted the orange lid a bit, because the platform knob was too thick. This is a thinner one, made with a filed down M10 bolt and a simple Tinkercad .stl-fil. My lid stays put!
