There are gift card for five different amounts of uses: 1, 2, 3, 5 and 10.

The card is a standard credit card sized, 0.8mm thick with the text boxes being 0.4mm. The texts and tabs are 0.4mm high on the card. So if you set filament changes at 0.4mm and 0.8mm, you'll get the card face, text areas and texts all in different colors like in the model pictures!

Use a marker to fill the text areas, or use PrusaSlicer's text tool! If you set the text height to 0.4mm, you'll get text with the card color, and set it higher for the same color as the other texts.
