Hi guys, I am overseeing production of these cases. The 60% size accommodates HHKB and Poker perfectly. I would provide dimensions, but the thing is - they're misleading, because the inside of the case is what matters and doesn't really have a "fixed" size. It stretches and forms around the keyboard. That said, it is designed for Poker/HHKB and other keyboards of the same size (Pure, V60, etc). They won't fit your keyboard if you're using a big custom case.
The 40% works for Planck and JD40, yes.
The Ergodox design has a divider inside, with pockets for both halves, yes.
I will speak to Massdrop about adding a FC660C/Magicforce option.
intelli78Thanks! And I have one dumb question if you don't mind. The black fleece interior won't stain the keyboard right? I've read that the Grifiti Chiton sleeve, which uses Neoprene lining, will stain the keyboards black. I'm not sure if fleece would do the same since I'm not familiar with any of these materials.
