Some company did this. The problem with 3d printed anythings is that they look fake. They don't make mistakes and mistakes is what makes things look natural. You need a sculptor to make a penis reeeeally look like a penis IMO. Though they make Willy in a Can which is a silicon you can mix at home in a can and then you get a willing cis-male to um *cough* stick his willy in the can. It makes a mold of him and then you fill it with the silicon that comes with and you get a perfect copy. It's meant for woman whose husbands are away at war or otherwise not available so they can 're-create' their partner, if you catch my drift. In any case, I don't see why a maker hasn't just gotten a cis-man to stick his 'bits' into a tupperware of Alginate yet.... Tada, a perfect copy of a penis, no sculpting, no errors... If I knew more about the types of silicon being used to make 'like real' prosthesis hell I'd have my own brand out there. If you could figure it out hell you could even make a 3 in 1, easy.
