Threaded Bushing Generator for Blender

A professional parametric tool to generate precise 3D-printable bolts, nuts, and threaded bushings instantly.

⚙️ Stop Modeling Threads Manually! ⚙️

Threaded Bushing Generator is a lightweight yet powerful Blender add-on designed for 3D modelers, engineers, and 3D printing enthusiasts.

Modeling precise mechanical threads takes time and boolean operations often result in messy geometry. This tool solves that problem. With a single click, you can generate complex mechanical assemblies with clean topology and precise control over every dimension.

✨ Key Features

• 🔩 Fully Parametric: Adjust radius, height, thickness, and smoothness (segments) on the fly.
• 🎛️ Dual Control (New!): Configure the Nut and Bolt independently. Need a tall bolt with a thin nut? No problem – specific settings for each part.
• 🖨️ 3D Print Ready: Includes a dedicated Clearance slider. Essential for 3D printing tolerances – ensures your parts fit together perfectly after printing without sanding.
• 📏 Advanced Thread Control: Customizable Thread Size and Pitch (distance between threads).
• 🔘 Washer Integration: Built-in washer generator with adjustable radius and height.
• 🌍 Multi-Language: The interface automatically adapts to your language (English, Polish, German, French, Spanish, Chinese, Arabic).
• 🎨 Visual Feedback: Generates objects with predefined vertex colors (Green for thread, Blue for core) for instant visual clarity.

🛠️ How it Works

1. Open the 3D Viewport sidebar (press N).
2. Go to the Generator tab.
3. Set your desired Fi (Radius).
4. Adjust Bolt and Nut parameters separately.
5. Click GENERATE.

You get a clean mesh, ready for export or further modeling.
