The model should be printed with a filament change. For a smooth surface, consider enabling ironing.

There are two models, one relatively thick at 3.2mm because I wanted enough layers for the white to have a good contrast with the green.

Use the model marked as ‘thinner’ if you don't want to use so much filament, it's 2mm thick overall.

I created this sign as a decorative anniversary gift for my friends who honeymooned in California.
