a friend of mine designed a molded plastic pulley with a wingnut cast into it so he could thread in a set screw. Has anyone tried doing something similar with a printed part? That is, designing in a hexagonal cavity, programming in a pause in the printing and putting a hexnut in the middle of a part and then continuing the print?
Just an idea, another use that comes to mind is putting a metal dowel pin in place after you've printed the bottom half of a hole so you can have more accurate holes on the side of the part. Thoughts? Experiences?
