There are pretty well defined bylaws that can allow students to play up to 7 seasons....normally 6 (non-covid). Most common 5 though.
But yeah, it's gotten very flexible. Not that I care a ton either way, but it would seem the player would need to at least be a legit student, studying in a program, but not some 2nd and 3rd grad degree as a ploy.
Check out Bambu Labs for a 3D printer. They're very good. One needs to be proficient in 3D cad in order to really use them. My son prints some really cool stuff. There's different filaments that allow one to print all kinds of stuff. If you have any other questions, just tag me and if I can't answer I'll ask my son.
