Updates… I have added two other versions.
Standard: 4mm H with border and content raised 2mm.
Flat: 4mm flat. The STL may look empty but the shapes are there if you float over for coloring. You can print upright, like in the included 3mf, or flip it face down and print for a smooth or textured finish.
Embossed: 4mm flat with content embossed 1mm. The border is flat but the rest is not.
The author marked this model as their own original creation.
