Edit Custom Worm Gear

AIQuery:Generate a parametric worm gear set and mounting bracket for a bipedal robot joint. Part 1 (Worm): Single-start worm gear, module 1.0, pitch diameter 12mm, overall length 18mm. The center bore must have a cutout designed to press-fit and screw into a standard straight plastic MG90S micro servo horn. Part 2 (Worm Wheel): 20 teeth mating worm wheel, module 1.0, pitch diameter 20mm, face width 8mm. The center axis must feature a 6mm D-shaft bore to directly mount a standard external rotary potentiometer for absolute angle feedback. Part 3 (Housing/Bracket): A compact, rigid housing that mounts the MG90S servo holding the worm gear, and holds the worm wheel perpendicular to it. The exact center distance between the worm axis and worm wheel axis must be fixed at 16.2mm (inclusive of a 0.2mm tolerance for FDM 3D printing). The housing should include flat mounting tabs to attach to the robot's leg structure. Ensure all geometries are optimized to be 3D printed flat on the build plate without requiring supports.
