Print in two colours so that the numbers are easily visible. These are made in PLA.
The author remixed this model.
The original lettering was removed as they were too small to print using FDM. I used Prusa Slicer to cut the model just below the labels and lines. Then I used Prusa Slicer's text tool to add the dimensions in deboss. Arial Black 6mm high letters were used. The templates come out better in two colours.
