Print as shown: rim on the bed, edge facing up, no supports needed. Use PLA or PETG, ideally one approved for food contact. Wash by hand in lukewarm water, not in the dishwasher. Layer lines can hold crumbs – to be safe, put cling film over the dough before cutting. 3MF keeps the parts apart and in millimetres. Every slicer opens 3MF and STL.
