From the project

Ergonomic monosplit keyboard on kailh choc switches

The Chocofly is an ergonomic monosplit keyboard with 4x6 column staggered keys, 4 thumb keys and 2 additional inner keys for the index finger (60 keys total) plus one rotary encoder.

The main idea of the Chocofly is to be thin and suitable for "sonshi"-style usage (putting it ontop the laptop keyboard). It is also pretty minimalistic - no LEDs/OLEDs/labels on keycaps/wires... and in my build it even has no case. It's just a pcb with switches on top of it and small silicone legs on the bottom. And this setup works pefectly! Well, for me at least.
