📌 Single Actuator Finger - Fully 3D Printed | Snap-Fit Design

This is a fully 3D printed robotic finger designed in SolidWorks, optimized for easy printing and quick assembly. It requires no metal parts—everything is made from PLA. With only one actuator input, the finger mimics the motion of a real finger using a scissor-like linkage mechanism.

🔧 Key Features:

✅ Single actuator operation (ideal for compact robotic hands)
✅ Snap-fit joints for fast, tool-free assembly
✅ No screws, no metal—100% PLA
✅ Modular & extendable design
✅ Tested for smooth flexing and return

The internal linkages provide synchronized bending using a single pulling or pushing motion, ideal for use in robotic grippers, prosthetics, or educational projects. The design balances strength and simplicity while offering flexibility for scaling or modifying the finger’s length.

Assembly Time: < 5 minutes
Skill Level: Easy
Print Settings: PLA, 0.2 mm layer height recommended
