MakerGear M2 Glass Tray

Sometimes if I'm printing one print after the other I don't like to wait for everything to cool
down. Seems like a waste of energy. So I keep a spare glass plate handy, and ready, so I
can swap it in place and continue on to the next print.
I made this holder for two glass plates. They are held at a slight angle in case I have them
coated with Elmer's glue so they don't rub up against the side of the tray.
This assumes you have glass plates that are fairly close tolerance to one
