GMK Nautilus Nightmares

“From a caprice of nature, not from the ignorance of man. Not a mistake has been made in the working. But we cannot prevent equilibrium from producing its effects. We may brave human laws, but we cannot resist natural ones.
– Captain Nemo, 20,000 Leagues Under the Sea

Inspired by deep sea monsters and ocean calamities, GMK Nautilus Nightmares is a continuation of the 2017 project featuring a brand new colorway and novelties.

Available for pre-order this December at Drop

Proposed Kits


The Core Kit is the starting point for everyone. Composed by 136 keys, it provides basic layout coverage for boards ranging from 60%, 65%, 75%, TKL, 96-key, 1800, CP and Fullsize layouts in both standard and winkeyless variants.
Some notable inclusions are the accent enter and escape, split backspace and stepped caps lock keys.


The Forties kit provides extra layout coverage for many small form factor and ortholinear keyboards, including Planck , Minorca, Sebright or Percebe. The kit includes small space keys, and Enter and Escape accent keycaps.


This add-on kit extends Core’s layout support by providing multiple shift keys in 2.25, 2.00 and 1.00 units sizes for FC660-like and 60% keyboards with arrows, small space keys and a second B for split and ergonomic keyboards such as the EM7, Alice or Lubrigante, and extra layout coverage for 60%, 65% and 75% keyboards.


The ISO kit adds layout support for German and UK ISO keyboards.


Featuring the Nautilus submarine, Kraken and Giant Waves, the novelties add will give you the extra touch to take your keyboard even deeper under the stormy ocean.

Space Keys

The space keys includes accent space keys from 1.00C to 7.00C for both standard, split, and 40% keyboards. On top of that, this kit will extend your layout coverage by including two 6.00C space bars so you can cover an HHKB or Cherry G80-1800 keyboards.
