Where I live sheets of butter cost three times more than the sticks I can buy in the store so I made this in TinkerCad to turn sticks into sheets. Leave the butter out at room temperature long enough for it to get soft. Put plastic wrap or cling wrap in the mold. (Never use filament printed items for food. They are pourous amongst other problems, which makes them unsafe for direct food contact.) Put the butter sticks in the mold unwrapped. Use the lid (covered in plastic wrap) to press down the butter into a sheet. Put cling wrap on top and do more sheets if you want. Freeze the butter in the plastic wrap and you have a frozen butter sheet ready for pastry making. Enjoy.
