This is a design of a holder for the plateau and aluminium foil for the anycubic wash and cure station.

The tighter fit is a smaller gap for the plateau, so it doesn't lean forward as much as others.

Also the 2 hooks that hold everything to the led collum is a tight fit. (when you put it in position, you have to place it one by one over the screws in the collum. the hooks are a little flexible, do it with care and it will zit t the bottom without wonky around)
