Arms can’t actually pivot with out breaking off
Tried printing with .4 nozzle, .15 and .1 detail in Prusa slicer with overture matte brown and it failed to be pivoted on both prints and just breaks off.
Additionally head is top heavy and tips over.
We reviewed Zhang Xin's report and corrected the problem.
Thanks for reporting the problem.
We checked with Cura, prusaslicer and Simplify3D.

Merry christmas.
