Filament: white PLA Layer height: 0.2mm Printing surface: glass Object consists of 3 parts. All parts already have an 'anti-foot' chamfer, at the bottom. Make sure to rotate the top and bottom part such that the flat face is on the printing surface. Put the middle part between the other two parts. Than glue the top and bottom parts together with superglue. To make the lines and notes visible, you can: a.) print the top and bottom parts with two filaments of different colors by stopping the print at an appropriate height and swapping the filaments, b.) simply color them with a sharpie.
