Here is a nice creepy, reaching hand that probably has many uses.
I'm thinking it would look great bursting out of a zombie themed birthday cake or meshed together with other 3D files. I included a second version with a base and screw holes so it can be attached to the wall and hold things. I use one to hold my headphones.
When printing with support, it creates a small section to support the tip of the ring finger but probably is not necessary.
This was a plaster model scanned with the Next Engine 3D scanner and then cleaned up in Mesh Mixer.
