Printed on a Flashforge Creator in PLA @ 0.16mm and NinjaFlex @0.3mm. I'm using regular cord instead of flexible filament for tendons to provide tighter grip. Problem with the flexible tendons is that it would require a much greater range of motion in the wrist to operate if this is made into an actual prosthetic.
