2015-11-23 (M) Desktop Chording Keyboard

Wooden keys had a great feel and appearance but the effort to recreate the unit was high. In order to provide inexpensive solutions to people who may have disorders associated with typing a 3D model was created which uses simple hardware to make a desktop keyboard. In addition to being similar in design to the wooden version this model can angle the base for even more relaxed typing. The angle base brings the keys up to the user and allows him or her to cup the keys with bent fingers rather than a splayed hand which was necessary for the wooden version and traditional keyboards.

Variability of base angle

Animated images were made showing the ability to change the base angle. The maximum angle was 37º but someone could increase that if necessary by investigating and changing the code. Below is a rotating view which shows a 15º base which should be a marked improvement over the flat wood version. To connect the pieces long #6-32 bolts and nuts would be necessary. Spacers were built into the pieces so only nuts and bolts are needed. No special tools are needed but a wrench capable of holding a #6 nut would be helpful.
