Z-Shim for Flashforge With Dual Extruder

I modified some of the earlier ones because 1) there were some screws that would get stuck 2) The board the z-shim sits on is thinner than the others seem to be designed for (so it would move a lot), 3) I wanted a handle because otherwise its impossible to get out and 4) I wanted it to sit on the side rails so it wouldn't wobble as much.

I'm using a 3mm glass bed although I had to lower my nozzles and loosen the springs on the bed all the way to get the bed high enough. It might be worth maki
