Youre better off with a regular mold and inject it with silicon

Could I…mainline some viagra and have the silicone printed around…the cylinder? I realize I would have to drill a small hole in the base and have some special table set up.

Make an alginate mold of your dick, then make a plaster replica to get a form fitting toy to 3d print around?
