Snapmaker U1 Build Plate Storage

Hold up to 4 build plates for the snapmaker U1. This is intended to be used horizontally, for example being stored on a shelf near the printer. The full depth storage exceeds the print height of the U1 itself, but fits on bambu H2 series printer. I have included a second build plate with a slightly smaller version that doesn't go quite to full depth that is printable on the U1 itself.
