I remixed Matthieu Milinaire's model of a simple gameboy and turned it into a name tag. There is a large space left open beneath the words:

"Hello!

My Name Is:"

which is designated to the name of the wearer.

If you want to print the model with your name already on it instead of writing your name or using a label/sticker, you can type your name into this custom font: https://www.fontspace.com/gamegirl-classic-font-f3331

Once you save the image of your text, you can either use a tool that may be built into your CAD software (depending on which software you use) or you could use convertio (below) to turn the image of your text into an svg file which can be easily imported to almost all CAD software programs.
