What I print to sell
Designs whose license allows selling: CC0 and public domain, CC BY, CC BY-SA, GPL, LGPL, MIT, BSD, my own designs, and designs with a purchased commercial license. CC BY-ND only unmodified and at the original size.
I don't print to sell designs with NonCommercial (NC) licenses, personal-use or all-rights-reserved licenses, unknown licenses, or anything showing other people's characters, brands or logos.
For your own file or a link, I check the license before printing.
