I made these for my mother who enjoys playing bridge and wanted something unique. They are designed to print together with 1 color change, red first then black. After that they are ready to hang on ear wires.
I am including a sliced file with the color change set at 1.6mm. This is a fast print. I have been doing it in PLA at .20 mm layers with just a skirt.
