Just wondering if this is illegal or frowned upon: Situation: Paper Craft Modeller buys a paper craft model. He sees that this paper craft model has a potential to be a base template for making other designs and models with the same theme. When said modeller was able to make the different designs from the said original paper craft model, he posts it and makes it available for those who asks for the variatons and distributes it for free. The original paper craft model of course is not for free distribution. Is this frowned upon? Just asking. Thanks!
