Designed and Printed for an Ender 3 Bed (220.0 X 220.0)

You will need good bed adhesion for this as it basically covers the entire bed. 

1.0 Nozzle for Box

.8 Nozzle for Lid

I used bigger nozzles so they would print faster. 

Don't mind the White on one of the Boxes, I ran out of Red filament halfway through and had to hot swap to white.
