Adjustable hand grippers are a simple and efficient way to train grip strength, but most models have handles that are too small for comfortable use. Here’s a parametric set of handle extenders designed to significantly improve ergonomics, contact area, and overall usability.
Designed for quick iteration and easy customization — adjust parameters in the SCAD file to match your specific gripper or preferred feel.
What’s included:
2 ready-to-print STL files (Handle A / Handle B variants)
Full OpenSCAD source file for easy adjustments (fit, thickness, curvature, ergonomics)
Printing notes:
Highly recommended - to improve grip, enable Fuzzy Skin in your slicer:
Thickness: 0.15 mm
Point distance: 0.2 mm
This produces a subtle textured surface that feels much better in hand
