Hi, the tip button is shown when you download the model. An encouragement appears to "show some love" and tip the designer, see attached file. ;)
As a designer I am free to chose which licence I want for my design unless I base it directly upon another design, then I need to use the same open source license. Which license each design has is shown for each model on thingiverse, a nice and descriptive instruction on what the license means is shown if you click on it. Kudos to thingiverse for making it so easy to use.
Some designs I do choose to let go totally free for others to manipulate and sell but others I want to keep as my own. The reasons for what license I choose differs but that is actually totally up to me. The alternative would for me to keep all designs for myself. Having free designs available makes it easy for other to take advantage of and it happens every week that I see my designs being sold for commercial purposes which in fact is taking advantage of my hard work without anything in return, not even a credit which ALL licences demand.
Did you leave credits to me when you tried to sell it?
