Thread Generator - Parametric Threaded Rods & Nuts
Print Profile(1)
Description
Looking for Threads? Look no further.
This OpenSCAD script lets you generate a variety of fully parametric threaded rods and nuts using BOSL2. It supports Triangular (ISO/UTS), Trapezoidal, ACME, Buttress, and Square threads, allowing precise customization of dimensions, thread types, and additional options for 3D printing. Whether you’re designing for lead screws, fasteners, or mechanical power transmission, this script has you covered.

🚀 Quick Start
1. Select a Thread Type
Choose the thread to apply to the rod and nut. Adjust general parameters like diameter, pitch, thread starts and direction, and blunt start options.
2. Customize Your Threaded Component
Each thread type has its own unique options:
- Rods: Set length, pitch, thread type, number of starts, and optional split feature for 3D printing.
- Nuts: Choose between hex or square shapes, adjust thickness, bevel options, and control 3D printing clearance.
3. Render and Export
Generate your threaded components at the desired resolution and export for slicing and printing. Using a fine layer height improves detail and fit. Increasing sparse infill increases strength.

🌀 Thread Types
| Type | Flank angle | Standard | Description | Application |
| Triangular / V-groove | 60° | ISO/UTS | Standard fastening thread with high grip strength. | Screws, bolts, general fastening |
| Trapezoidal | 30° | ISO 2904 | Power transmission thread with high load capacity. | Lead screws, actuators, CNC |
| ACME | 29° | ANSI B1.5 | Strong trapezoidal thread for smoother motion and durability. | Machinery, high-load lead screws |
| Buttress | 45° / 7° | ISO 103 | Asymmetric thread for high axial force in one direction. | Jacks, presses, heavy machinery |
| Square | 0° | None | Most efficient power thread with low friction. | Precision lead screws, high-force applications |
