wanhao i3+ 4mm z-stop spacer

At first, I tried moving the z-stop with the provided extra holes on the printer, but for some reason, non of the holes fit my 4mm glass plate very vell.

I knew I had seen a z-stop spacer thingy here before, and after a search I found Shuraks part. That part was not enough, so I decided to make my own loosely inspired by the original.
