Maker Faire Badge

I am taking my son to the NYC Maker Faire for his birthday present, and made him this badge as a physical token. It worked - he has been giggling for days. OK, the print is a little messy, but he's 7, loves tech and 3d printing, and the badge glows in the dark!

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/9aduw7zYExJ

Instructions

Print. Swap filament as soon as you see that it's done printing the background, and the lettering will come out contrasting.

Then stick a button pin on the back (they sell them in art supply stores), and wear it with pride!
