About this 3D model

This is an invention that is supposed to help the blind, by allowing them to read the keys on the keyboard. These keys are the universal size, so they will fit on any keyboard. The keys also print with the number keys which will fit on both the desktop key pad or a laptop number pad. The keyboard shown in the picture is the Dell Wired Keyboard KB216 (580-ADMT). To attatch the keys to the keyboard use either super glue, or I would reccomend double sided tape for a temporary job. To attach them in the correct direction use the pictures of the keys on the keyboard.
