Print settings

Print it with two colour changes so the middle layers are a different colour than the top and bottom to make the numbers easy to read.

The one in the picture is printed with Prusament Galaxy Black, Galaxy Silver and Fillamentum Melon Yellow.

If you decide to use it make sure it is legal in your area and use filament that can withstand being in the sun in a hot car. Can be attached to the windshield with double-sided adhesive like a typical parking disc.
