M1 × 0.25 mm Screw and Nut (3D Printable, ISO Metric Thread)

This model includes:

✅ 1x M1 × 0.25 mm ISO thread screw ✅ 1x M1 nut

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

Micro thread calibration

Miniature mechanisms

Educational demonstration

Printer fine tuning for ultra-fine details

Dimensions

M1 Screw:

Outer diameter (head/hex or full feature): ~2.16 mm

Inner thread core (expected): ~0.75 mm (M1 thread core)

Print Settings

Layer height: 0.05–0.1 mm (very fine required!)

Infill: ≥80%

Supports: Not required

Recommended materials: PLA+, PETG, ABS → ultra-fine nozzle (≤ 0.4 mm recommended)

Tolerance tip: You may need to adjust flow rate and Z offset for best fit on such small parts.

Notes

Due to the very small size of the M1 thread, a finely tuned printer is essential. Ideal for testing printer precision , or for demonstration models . This is not suitable for heavy mechanical loads — more for precision testing and calibration.
