Intro:
The wrist with 3 DOF has a bend range of 100 degree in all direction and 170 degree at max which determined by the dimensions of the structure.
It can be used as the wrist with 3 DOF together with a Cardan joint. Then it can realize the function similar to human's shoulder joint.
可与万向节组合实现人类肩关节功能。
No further geometric analysis on the relation between dimensions and range (Im lazy and tired of math).

Statement:
The model is an anti-engineering
