70mm TPU Squeeze Stress Ball 3D Lattice Sphere STL OBJ 3D print model

This is a 3D printable lattice stress ball designed for flexible materials such as TPU (Shore 95A recommended). The geodesic frame structure provides a firm but squeezable grip, making it suitable both as a stress relief toy and a light hand grip trainer.

Features:

Procedural lattice sphere structure (clean geometry, optimized for FDM printing)

Diameter: scalable (recommended 60–80 mm for best squeeze feel)

Frame thickness: ~3.5 mm (balanced between durability and flexibility)

Designed for TPU or other flexible filaments (Shore 90A–95A tested)

Printable in two halves (hemisphere split) for easier assembly and air-sealed squeeze effect

Applications:

Stress relief ball / fidget toy

Hand grip trainer (light to medium resistance)

Showcase of TPU printing capability (functional demo print)

Educational or decorative geometric object

Files Included:

.STL (ready to print)

.OBJ (for editing/customization)
