Manually Refresh-able Braille

thingiverse

A key aspect of a Senior Capstone design project is the development of an affordable Braille display, showcased through an early prototype of its control mechanism. Despite challenges in printing at standard Braille size, it can still be used to demonstrate concepts or experiment with. Jumbo Braille (1.3:1) prints well while 2:1 prints even better though it deviates from the standard. The inspiration for this control mechanism comes from a diagram found at http://www.kscitech.com/BBT/Slider_diagram1.jpg. To achieve optimal results, print with holes down (inverted). Holes may require reaming using a drill bit to ensure proper size. Additionally, the pins on the first layer can be too wide; trimming off a small piece from two opposing sides helps them fit better.
