TIL. ThatIf you're referring to the DCS sculpted keycaps which come with the EZ[2], they're still not quite the same. Keyboard.io Models 01 and 100 use different shapes for (nearly?) every key. At the edges of the keyboard, it's particularly noticeable: the outer edges are ramped inwards.

The downside of individually sculpted caps is, of course, compatibility with other keycap sets.
