Endstop Axis Z

My fourth update for my Anet A8 Plus is for the Z axis limit switch. I use a very thin PEI sheet without glass when I am going to print ABS, ASA or other material that needs a good heated bed and a glass bed with a flexible coating for PLA. It really was very difficult and tiring having to loosen and tighten the screws on the standard microswitch bracket that came with the Anet.
