Summary

A practical, artistic, and creepy remix of these hands from cults3D: https://cults3d.com/en/3d-model/art/2-male-hands. For the base I used four drywall anchors and wood screws to wall mount the base. Then, just slide the hand right on.

The four files you'll want to print: Right_hand_v2, Right_hand_base, Left_hand, Left_hand_base

2/4/25 UPDATE: Looks like I accidently uploaded the wrong right hand file! For anyone who has already printed the right_hand_v1 (which I've replaced with Right_hand_v2) and still want to make use of the older version of the hand, I've recreated the old base for it, just in case.
