Add braille to all the signs

thingiverse

Do some good with the school 3D printer - those signs could use some braille for visually impaired students, and there's no harm in teaching sighted students how to read braille themselves... How I Designed This I designed this out the hard way in FreeCAD; two layers, filleted the braille. Making Braille Signs Objectives Students participating in this will gain a basic knowledge of braille while making the school campus more accessible. Audiences With proper parametric setup, even an introductory student can make these signs - but for a challenge, advanced students could print these in alternating colors from scratch. Preparation The text of the sign and its proper braille translation will be needed for each sign - watch that last bit like a hawk, I would definitely have snuck in a braille fart joke if I didn't think the teacher was paying attention. Steps! Measure the sign to be made/replaced Sketch out a rectangle (or other shape!) to be the base Pad that rectangle to whatever depth is desired (0.1" is pretty thick) Add another sketch with the text and braille Pad this out appropriately Fillet down the edges of the braille. (You can chamfer the text as well if you like) Results Students gain an appreciation for braille and a rudimentary knowledge of what it looks like and what it does; your campus becomes a little bit more friendly to the visually impaired.
