About
This free 3D print machine screw and nut generator creates custom threaded fasteners based on ISO metric proportions, making it useful for custom hardware prototypes, oversized display screws, cosplay parts, classroom demos, and light-duty printed assemblies. You can choose common M-size presets, control screw length, switch bolt and nut styles, and tune tolerance so the printed threads fit your printer, filament, and layer height.
The generator exports separate STL or 3MF files for the bolt and nut, so the parts drop cleanly into PrusaSlicer, Bambu Studio, Cura, and OrcaSlicer workflows. If you need printable metric bolts, custom plastic nuts, or a fast way to test thread pitch and clearance before machining or ordering hardware, this page gives you a quick way to generate them.
