Nice I really want to build one but I think I'd much rather buy the parts in a kit than separately. I saw this wooden case[0] in a tweet and I think I'd want to try my hand with that instead of the 3D printing.
Registration is required for MassDrop, which is unfortunate - but they have to do that to be classified as something other than a retailer so they can offer lower prices.
Unfortunately I haven't seen it for sale on Massdrop since I've registered months ago... Of all the mechanical keyboard designs I've seen, that's the only one that makes sense to me ergonomically.
