About this 3D model

Part of a Senior Capstone design project to make a low cost Braille display. This is an early prototype of the control mechanism, but still useful to demonstrate the idea, or play with. Files are 1:1 for standard Braille, but this is very difficult to print. Jumbo Braille is 1.3:1 and prints ok. 2:1 prints very well, but is not a standard Braille size. Original idea for control mechanism from: http://www.kscitech.com/BBT/Slider_diagram1.jpg
