I really like a board game. This game includes artistic references (as parody) to a well-known movie.
I wanted to improve the pieces of the board game (which were 2-dimensional) to augment my own experience playing it. This led me to create a 3D printable model of a ship from the movie that modeled the parody's artwork (which has significant differences from the movie, but is still recognizable as a ship from the movie, as its intent is parody).
In order to accomplish this, I started with a fan-made model of the ship from the original movie that I found on Thingiverse. I altered it significantly in order to match the parody's artistic style and to work as a printable game piece.
The fan's model has an Attribution-NonCommercial license on it.
I played the board game with some of my friends. Some of my friends want to pay me to make them their own copies of the game pieces, which includes (among many things) this ship.
My four questions: (1) Is my creation of this game piece considered parody because I am very explicitly copying parody? If so it might allow me to be able to sell these pieces under the "fair use" clause. http://lemoinefirm.com/parody-fair-use-or-copyright-infringement
(2) What about if I get permission to sell? Who's permission would I need: the parody game maker's? The fan's, who modeled the spaceship? Or the makers of the movie themselves?
(3) Does the fan have the right to put a copyright license on his model of the ship in the first place because he is explicitly copying someone else? Or is his work considered art?
(4) Has my work been altered enough (now that it distinctly resembles the parody and not the model I used) that it is considered new artwork that has my copyright, not the fan's? https://www.wildlifeartstore.com/can-you-copy-art/
