Simple Artificial Limb. Arm prosthesis

Hello

I present to you a simple prosthesis that I printed for my friend. I just couldn't bear the thought of him not being able to drink beer normally.

The prosthesis was supposed to be simple and easy to use, and additionally developed as the need arises (if someone doesn't like beer and prefers tea)

If you guys are willing to help and design tips for this prosthesis or modify it let me know it would be really cool.

Or maybe someone unknown will be able to enjoy a "normal moment"

Greetings
