This design I made works as date cubes. Turn them every day to show the current date. Months included!- Make sure the month bars read upwards from the printer bed.- The month bars do not need infill.- The date cubes have to be printed with the 1 facing down on the printer bed- The date cubes do need infil 10% worked really nice for me.- You could use support for the 1, might look better, use low support percentage though.
