| Based on this sketch
from Alex, I used Fusion to design the
parts, lasercut them out of 1/8" plywood.
All the little holes are for 1/8" dowels.

| Last year, I saw that the servo arm that came with the servo was too short to fully flex the fingers. So I printed some new ones. They have different inside diameters, to determine which one would fit snugly on the servo shaft. D is the best, E,F too loose, A-C too small.
