I wanted a bed plate holder that mounted to the wall and could hold 5-6 plates. I couldn't find any i really liked so i made this one. It will hold up to 6 if you use thin enough screws on the top or 5 if you don't. Printed vertically with supports with 0.265mm top and bottom z spacing and it came out perfect.
This was modeled to fit Hi build plates. I am sure you could put basically any build plates on it. I made small chamfers on the inside where the plate actually sits so if you place a Hi build plate in, front down, it sort of holds in centered in place.
