The model was scaled by a factor of 1.10 to compensate for shrinkage. The thumb base part had to be cut in two pieces to address a design error issue. Loctite blue was used to prevent the screws/hex nuts from falling out. I ran out of metal bearings, so I had to print a temporary replacement part. The "hook" part is used to tether the fishing line to the tip of the finger. Then "ring" is used to ease the model manipulation. Epoxy was used to glue parts and re-enforce weak points.
