Short Temper

Published: 6 November 2026

Short Temper is a Temper, a 36-key wireless split keyboard, with my own ZMK config. It has no number row. The thumbs reach four layers, and each lasts while its thumb key is held.

Exported from the Blender scene behind the renders. The case and keys come from the holster's CadQuery model.

The screens

Each half takes an optional nice!view screen, and the same firmware runs with or without them. On Base they show the batteries, Bluetooth slot and held modifiers, and which thumbs reach each layer. While a layer is held, they show its keys.

The holster

I also designed a holster in CadQuery for wearing the keyboard on my legs, one half on each. A J-shaped clip hooks over the pocket edge, and the keyboard sits keys out and thumbs up, so a hanging hand meets the keys the way it does at a desk. It lifts straight out for desk use. So far I’ve printed a test fit, and the keyboard fits it.
