I saw a maker the other day that released his plans on his project with a non-commercial license. He later found it was being sold on Amazon. He contacted an attorney friend of his, the attorneys said that the maker licensees are only truly effective on art.

If it’s a physical functional product, you have very little in the way of legal protection from a creative common license, which kind of sucks because the proper legal method would then be patent, but that puts us in the same scenario that you can’t copy it for a non-profit.
