Jerry's Middle Phalanx Amputation

thingiverse

This modification of Knick's Prosthetic Finger builds upon the original design by Knick - Middle phalanx amputation, courtesy of Yair Herbst. Enable Evansville, Kenzie's Helping Hands, and Jerry contributed to the work. The recipient suffered from amputations on both index and middle fingers, leaving behind a functional proximal knuckle, while their ring finger was entirely lost. This modification leverages components from an earlier version - Jerry's Knick Finger, originally designed for the ring finger. However, this tip is not included in the current file. Key features of this revised design include: * A keyhole connection linking the tip knuckle and the tip for effortless assembly and a firmer grip. * Integrated pin connections for both joints to enhance stability. * A knob secures the string under tension for added durability. * Larger holes for the elastic ensure accurate printing, preventing common mistakes. * A flexible sleeve fits snugly inside a PLA piece for enhanced comfort. Files were created using Fusion, incorporating various parametric features. Two versions of STL files are provided: one with an adjustable mid-section to accommodate different residual limbs and another scaled to match preferred finger circumference. To achieve optimal results, the flexi piece should be printed in flexible material, while the tip (not included) should also be printed in a similar material. The remaining components can be printed using PLA. A picture illustrating an older version with red and yellow parts demonstrates how stringing issues were addressed in previous iterations.
