Key Hander

This is a big file, don't worry if it takes some time to download. The mesh has some errors but they do not compromise slicing and printing so do not worry.

I downloaded the original hand for free from:

I imported it in blender, rigged it, put it in a better pose, fixed some issues and added a base.  

I hope you like it!
