An e-NABLE Volunteer has a prosthetic hand recipient with missing fingers and a working thumb.  The first 3D printed Raptor hand proved to crowd the recipient's hand. This is just an estimated improvement quickly hacked up in Tinkercad.  It also includes a mating palm cushion.

The modified Raptor Hand has the same width and height as the 100% hand but the length has been stretched to 130% (red part in the illustration) without changing the holes for hinge pins (yellow parts in the illustration).  The length of the thumb opening was increased from about 27mm to about 46mm.

The palm cushion was based on the Raptor Adaptor palm cushion.
