It is a perfect butter dish measuring a German / European piece of butter measuring 100mm x 75mm x 38mm. In contrast to other known models, it leaves some space all around. It is also tight but has no step and is therefore easier to use. To make it easier to take it off the table, the edges are slightly raised.
I would print it on a textured PEI, that's how the parts are positioned too. PLA is not a suitable material because it cannot be put in the dishwasher. PETG is critical  but polycarbonate could be used. Translucent is very nice.
