3D Print Braille Keyboard - Yonas Y.

This short guide shows how to design simple, 3D-printable mechanical keyboard keycaps with Braille dots using Autodesk Fusion 360.

You'll need access to a 3d printer, filament to print with, a slicing application on your computer, and

Start a new sketch on the XZ plane. Draw a trapezoid that represents the side profile of the keycap, including the slight inward slope typical of mechanical keycaps. Fully constrain the sketch with dimensions.

Finish the sketch and use the Extrude tool to pull the profile into a 3D body. Extrude to the desired keycap width (usually around 18–19 mm for standard keys).

Apply Fillet to the top edges of the keycap. This softens the corners and gives the keycap a smooth, ergonomic feel similar to commercial keycaps.

Create small spheres or circular extrusions on the top surface. Position them according to the Braille character layout and adjust their height slightly so they are easy to feel but still comfortable to press.
