Did you lost or broke your Real Grade gunpla hands (it happens yes, it happens).

Now you can reprint the hands with your bambu-child with the common 0.4 nozzle (sure if you have 0.2 it will be better).

Attached the print in place 3D model, ready to print and to paint if you want,

the fists are fixed pose for use with weapons, the open hands are posable like the original one.

The stl model is reposable with a 3D modeling software, to look as your favorurite pose ("V" for victory would be an idea?)
