About this 3D model
Metacarpal Phalangeal Joint Pins: Pins for the Liam_finger_block.stl part that holds the 1st joint in. Not for heavy use. Proximal Interphalangeal Joint Pins: Pins for the Liam_1st_phalange.stl part that holds the 2nd joint in. Not for heavy use. These snap into place and won't fall out. I'll do thumb pins when I'm finished printing the rest of the hand.
