2015-08-03 (M) Wrist Mounted Chording Keyboard

Revisions were made to the thumb board. When attached to the rest of the assembly there was interference from the closest key lever, the index finger key, so unnecessary plastic was removed from the model. Instead of gaps between the switches dividers were added to hold the switches more securely. Clearance was added to account for printing errors.

Rotating model

A print was made of the thumb board and the middle switch fit securely which meant the margin of error was estimated well. Switches were glued in place since the print seemed usable. Red 6.0mm switches were used for the outside switches and a similar gray switch was used for the middle switch. Color was arbitrarily picked from stocked components. 4.5mm switches were also glued in place under the key levers for the fingers.
