I believe treble is not operating right now because they are renovating a new facility or something, he mentioned moving in around November so I would assume you should start bugging him around January or February at the earliest. Also if you are really interested in have a case for your HHKB I recommend that you take yours apart and look at the complexity of the case and then re-evaluate how much money you think it would cost to make considering: R&D, Testing, Tooling, Labor, Materials etc. . This is not a poker that just drops into a rectangle by any means. The case is also the top half of the switch housing. Bits will be broken, aluminum will be wasted, time will be lost, and aluminum cases will be freaking expensive so keep that in mind.
