BrailleGen

What is BrailleGen?

BrailleGen is a small open-source web app that turns typed text into a 3D-printable braille tile. It uses the liblouis translation library, so you can choose English UEB in Grade 1 or contracted Grade 2, as well as Spanish and French tables.

After entering your text you set the characters per line, dot height, plate thickness, line spacing and margins, then generate the model. A slab mode and a vertical export option help with different print orientations, and an export scale setting lets you match your slicer's units. The generator runs in the browser through WebAssembly, and the code is published on GitHub under the AGPL license.

It is useful for tactile labels on jars, switches and doors, or for teaching materials. The project is young and lightly documented, so print a small test tile first and ask a braille reader to check it before making a batch.
