I found a company called
PlexStyle .
Talked to them, they can make me a box, which costs 8$.
But i wanted to put a couple of words on one side, with 2 colors.
They said, if you can make it one color only, there's no problem, but if more than 1 color, it will cost an extra 20$.
I went for it.
Now i'm waiting for 3Dtek on my request to print the object.
