Made this today on my Thing-O-Matic for my youngsters. I matched the actual image more than making a threaded cone. This was printed in glow in the dark ABS and the chrome/silver was painted on with a paint pen. It is two separate pieces, the drill bit snaps into the base, It took about and hour and a half to print with a 50% fill. It has not been sanded or touched up at all... didn't even cut off the burrs.
