This model is part of a bionics project, intended to provide a below the shoulder amputee with a biomimetic prosthetic arm. For this hand model I isolated the bones from a CT scan of a human hand and remeshed them in blender.

I then designed a ligament sheath including the collateral ligaments, in order to hold the joints together. The bones were then 3D printed in PLA and the ligament sheath is set to be printed in a TPU soft filament.
