Being involved in both the 3d printing community and case building community for a couple of years now, I've learned one thing: people who print, don't like to pay for files and are not a good audience to sell to.Selling kits imho will indeed have a much higher chance at succes. Just realize that you're going to have to find a unique selling point. Plastic cases will need something to compete against metal cases as it has a worse starting ground.
