MJF printed manuform-esque ergoScaffolding style wireless split ergo endgame by phazerlock.
Inspired by the manuform, but implemented in openpyscad rather than closure. Sockets clip into the 3D printed housing but need to be held in with glue.
The two keys at the top of the thumb cluster are a reach, so the owner only uses them for macros. All the others are perfectly comfortable. Their placement was tweaked over about 4 iterations.
Features: MJF printed manuform-esque ergo. Larger through-hole nrf51822 a la mitosis. Kailh hotswap sockets for endgame compatibility.
