2015-08-29 (Sa) Wrist Mounted Chording Keyboard

The modeling file from 2015-08-11 (Tu) was reopened and modified. Two different types of servo lever arms were needed to make the four bar linkage. One type of lever must attach to a servo horn and be hinged on the other side. The second type must have bolt holes on each end to act as a hinge in both places. Two of each piece should be printed for a full set. Each piece is the same length so the four bar linkage being constructed would be a parallelogram.
