Ah okay, why not take this a step further and as I mentioned in previous post, make it so that it is "hot-swappable", so I can get a keycap from Binge with keycap, MX-stem, Alps stem, Topre stem, BS stem as an eg and swap as and when I wish.
If we work on this, this could well be the future standard, not for artisan keycaps, but regular keycaps as well.
Companis produce top half only, and then we can use the stem specific adapter, thus alleviating lack of keycaps for alps, topre, BS. Also, it would make it easier to produce, as there is only one standard that has to be followed.
