Customizable Keycaps (AEKI)

What is Customizable Keycaps (AEKI)?

Customizable Keycaps is a free MakerWorld customizer by the designer AEKI that builds a set of up to nine keycaps for Cherry MX style switches, each with one letter, emoji or symbol on top in a second color. It runs in MakerWorld's Parametric Model Maker, so there is no code to edit.

You type the characters, one per key, and pick a font that supports them: Noto Emoji for emoji, Noto Sans for text, Noto Sans TC for Chinese characters, two Noto symbol sets, or Yarndings 12, a dingbat font that turns letters into symbols. Then you set the text size, the keycap and character colors, how many keys you want and the keycap height, and press Generate. If a character shows up as a rectangle, the font you chose does not cover it.

It suits anyone who wants a few novelty keys for a mechanical keyboard or a small macro pad. The characters are flat color inlays rather than raised or engraved, so plan on an AMS or a manual filament change. Every key has the same single-unit shape with no profile or tilt options, and fit varies between keyboards, so print one test key first. The designer recommends a 0.2 mm nozzle for crisp characters, and you need a free MakerWorld account to generate and download.
