Little late to the party but I have a couple questions, do you know what size of holes the mics needed? I'm designing the holes pre print to save post processing time and was curious on if you remembered the dimensions for this brand of headset. My other question is on the rewiring? Is it needed outside the battery converter or is the slack optional? I have the idea to use an attachment for the mic on one of the sides but for the other side The default cables will probably reach for me. (The less soldering I do the better lol I am bad). Thanks for the great guide btw.
