Hi,
I've been reading a lot about keycap manufacturing, and I'm not quite sure about the method for making double shot keys such as O, D, and Q. My understanding is that the top of the cap is molded with a hole in it, to match the shape of the character, and then another piece is molded to fit that hole. But, lets say that you molded an "O". Wouldn't the middle of the O fall out before the other piece was inserted? It would be the same with D, Q, A, B and many other letters.
Thanks in advance!
