Here are the first 4 Zodiac Credit Cards.
With these cards you will be able to find them in the sky, comparing what you see with your 3d printed cards.
They are also a good collection for amateur astronomers and star lovers. Many more constelations will be uploaded in the next weeks (all the Zodiac signes are ready). You can keep some of them in your wallet, because they are the same size as credit cards!
You DON'T need an AMS for printing it bicolour (I don't have it), just pause the print at the 9th layer and change manually the filament.
Share and comment if you like it, and ask for your favorite constellations, I will be working on them.
