Flashforge Plate Thickness Adapter

Have a Flashforge Creator, or equivalent model? Want to put a glass plate (great for printing PLA, and nice if you want to be able to swap in and out build plates easily, for example if you have plates of differing materials, surfaces, surface textures or surface coatings) in your printer? Use this adapter on the rear board that hits the Z endstop. this "tricks" the printer into "thinking" the built plate is actually a quarter inch higher than it is, allowing you to then put a quarter inch thick piece of glass on top of the existing build plate.
