I don't think that's what he's asking about. What you guys are talking about are the same thing as the collar studs which keyboard keys would work great for, but i think he's talking about a detail that's molded into the codpiece itself. Am I right in thinking this wesari? I'm at work so I can't really attach pictures and what not, but there are 2 rectangular bumps molded into the cod. If you are scratch building then your approach seems the best to me, maybe others might have another idea.
