2015-08-01 (Sa) Wrist Mounted Chording Keyboard

Changes from version to version have been getting less dramatic. The built in spacer and axle were good additions and have been kept. A thick piece of plastic to press the tactile button was not necessary so it was reduced. Bolt holes were widened slightly to make assembly easier. The angle on the pieces was also increased to make a more relaxed fit.

A cone and peg were added to the flanged spacer. The flanged spacer was meant to be glued to the key lever arm piece after printing so it could be used as a pulley for deploying the lever arm. Ideally the lever arms would be automatically folded and unfolded as the keyboard was ready to be used or put away. The cone was meant to keep a pair of strings in line which would pull one direction or the other in order to deploy or retract the lever arms. If not needed the peg can be cut off and the cone ignored.
