Heathkit Hero Robot Wrist Body

This is a replacement wrist body for the Heathkit Hero Robot's arm. The two halves have the correct cutouts and slots to hold the original motors and bearings, except for the connection to the wrist pivot motor. On my robot, the wrist body was broken and that connector piece had long since been lost.

For the pivot motor connection, this design holds a 3 mm flange shaft coupling such as this one: https://www.aliexpress.com/item/3mm-Flange-Shaft-Coupling-Steel-Rigid-Flange-Plate-Shaft-Connect
