Large Hand created with Revo 3D scanner. The model has a large hand but can be scaled at will.
To make the hand more realistic I recommend printing it with this PLA https://amzn.eu/d/6iMbu7o or a skin-colored PLA.
The result is fantastic as you can see from this photo
Update:
User RodT created a wall mount for the hand. You can find it in the press profiles.
Personally tested, it fits perfectly in the hand to hang on the wall. (Unscaled hand)
ENJOY
