Keycap Generator (srwi)

What is Keycap Generator (srwi)?

Keycap Generator by srwi is a free browser tool that turns keycap shapes and your own legends into multi-color 3MF files. It works with three building blocks: a keycap model for the physical shape, a template that sets where each legend sits and in which font, size, angle and color, and the keys themselves, where you type a character or pick an icon from the Phosphor set. A template can hold several legends, so one key can carry a main label plus a secondary one in another color.

The built-in models are Joe Scotto's flat, scooped and sculpted (rows R1 to R5) profiles in widths from 1u to 3u plus 6.25u, 7u and 10u spacebars, along with one flat DSA key. You can also upload any keycap STL and rotate it into place. Six fonts are included and you can add your own TTF. Legends are cut into the top surface to a depth you set (1.2 mm for a new model) and filled in their own color. Presets for a numpad, a 40% ortholinear and a 60% ANSI board give you a full layout to edit.

Generate downloads a zip with one numbered 3MF per key, written with Bambu Studio metadata. It suits keyboard hobbyists with a multi-material printer who want matching custom legends without modeling each cap by hand.
