01 / BRIEF
A keyboard stripped of its old job and rebuilt as a controller for one person's workflows. Not a macro pad with sixteen shortcuts to memorize: modes and layers designed around how one specific human actually works, rebuilt every time that changes.
The premise is that general input devices are a compromise nobody has to accept anymore. If you can print the body and flash the firmware, the tool can be shaped to the hand and the habits instead of the other way around. The interesting part is not the keyboard. It is that hardware has become something you can iterate on with a diff.
02 / HOW IT WORKS
The body is source code. Every measurement is a variable in a parametric CAD file, not a shape dragged with a mouse. Change the tablet thickness and the jaw regenerates around it. Change the key pitch and the plate follows. The render on this page is generated from that same file, which is why it cannot go stale.
Printed at home, with the grain in the right place. The grip prints in carbon-fiber nylon, with the fiber running through the jaw arms where the load is and never across the antenna zone, where it would kill the radio. A printed gauge validates tolerances before anything real gets printed: you fit the actual tablet into a ladder of slots and the one that holds without forcing is the number that goes back into the source.
Layout follows the hand. The key field sits to the left of the screen, always, so the hand that holds the device is the hand that fires the actions. An encoder handles anything continuous. A light bar reports which mode is live, because a controller you have to look up is a controller you stop using.
Firmware and body iterate together. When the firmware changes how the hand rests, the grip gets reprinted. Hardware follows software here, not the other way around, and the printer in the next room is what makes that loop short enough to matter.
03 / DECISIONS
If a shortcut needs remembering, it is designed wrong. Anything that requires a cheat sheet gets redesigned instead of documented. That single rule has killed more features than it has kept.
Modes over combos. Chording is fast for the person who practiced it and useless for everyone else, including the same person six months later.
CAD as code. Every iteration is a diff, every measurement has a name, and the reason a dimension exists is written next to it.
Measure before you print. A gauge costs thirty minutes. A body that does not fit costs a night and a spool.
