About this generator

Keycap Legend Generator is a free browser tool from Vostok Labs that turns an icon, logo or letter into a printable mechanical keyboard keycap. You choose one of four profiles (Standard, Low, Thocky or Choc v1) and a size from 1u up to a 6.5u spacebar, then pick a legend from about 1,700 built-in icons, upload an SVG, or type a character in one of roughly 30 fonts or your own TTF or OTF file. A live 3D preview updates as you size, rotate, nudge or mirror the legend.

The download is a 3MF with the cap and the legend as two parts that already have colors assigned, so it slices as a two-color print. You can also make a shine-through cap for a backlit board or a single-color cap with a recessed legend. A stem fit setting and a printable fit test help you tune how tightly the cap grips your switches, and any cap can get a homing bump.

The web version needs no account. The same generator also runs inside Bambu Lab's MakerLab, where you sign in with MakerWorld and can buy a Pro Pack for whole-keyboard sets and a second legend on one cap. Both are free for personal use only; selling the prints needs a paid commercial license.

What you can make
