Vault boy from the Fallout computer game series. Don't mind that mushroom cloud, everything is A-OK. There are several other vault boy models posted on the site, what makes this one different is that rather than printed face down and flat, the black outline here is done in relief to give it a more interesting 3D texture.

There are two versions provided here to choose from, one has cutouts for 8x2mm cylindrical magnets, in case you want to stick it to your fridge (or vault door), and the other is just character with no cutouts on the back. If you want to scale to another size, you should use the version without magnet cutouts, then add them back in after scaling if you wish.

This model uses 6 colors, but could be easily reduced to 4 by making the teeth the same color as the face, and the shoes either black or matching his clothes. All colors are separate objects, so recoloring them is easy from the object list.

Better living underground!
