One thing to note if you are selling, the first issue you would have to deal with is the 3d artist, I subscribe to several on Patreon which offers a commercial licence but for things like The Hulk, I could also end up in a legal battle with Marvel/Disney if I sold them, thats not something I can afford so I just don’t risk it!
Reed Richards (Mr. Fantastic) made Bruce Banners pants. That's what I've heard anyway. ***Mister Fantastic later created a pair of super-stretchy pants for the Hulk from Unstable Molecules. Stan Lee once commented that he liked to work "science" into all of his stories, and that Hulk's pants were the only time that he didn't have a clue how the exact science behind it worked.***
