Index Finger Prosthetic (Entirely flexible filament)

thingiverse

This DIY approach creates an index finger prosthetic entirely out of flexible filament. Simply print, thread fishing line through the holes in the model - if needed, use a needle or small nail to widen them - secure at the tip of the index finger and attach the other end of the fishing line to a wearable wristband. Its functionality is comparable to the "Kinetic Finger" and utilizes a similar finger design as the "Flexy-Hand" prototype.
