Shoulder bearing mod Pivot motion

Decided to add 688ZZ bearings to the shoulders for the pivot motion for smoother movement and less wear on the shoulder. I printed these with 5 walls and .25 layer height with a .5 nozzle and 45% triangular infill. Put the washers between the bearing and the back and front chest plates. Also this is a remix of a previous bearing mod so those bearing will need to be bought also
