M3 × 0.5 mm Screw and Nut (3D Printable, ISO Metric Thread)

This model includes:

✅ 1x M3 × 0.5 mm ISO thread screw
✅ 1x M3 nut

Both parts are designed for 3D printing and are excellent for:

Thread calibration (especially for small threads)

Functional testing

Miniature mechanisms

Printer tuning

Dimensions

M3 Screw:
