🧰 Smart Parametric Enclosure & Junction Box Builder

First version Here.

The Ultimate Modular Solution for Electronics, Wiring, and Prototyping

🚀 Customizable. Precise. Professional.

The Smart Parametric Enclosure & Junction Box Builder is a powerful OpenSCAD project for makers, engineers, and electronics enthusiasts. Whether you're housing a microcontroller or building a control box for an industrial machine, this design adapts to your needs — over 40 configurable parameters, no CAD skills required.

🔧 Key Features & Customization Options

📐 Smart Sizing System

• 10 preset sizes (Mini to XL)
• Full custom dimensions (L: 50–200 mm, W: 40–150 mm, H: 30–100 mm)

🛠️ Mounting Options

• Wall-mount holes with adjustable spacing
• Corner mounting pillars (Ø6–15 mm)
• Optional M2–M5 threaded inserts

🧰 Advanced Lid System

• Recessed, flat, or raised lid options
• Lid thickness adjustable (1.5–5 mm)
• 4 screw head types: Phillips, Torx, Hex, Slot
• Choose between a snap-fit lid for quick assembly or a flat lid for a sleek, seamless finish

🔩 Internal Thread Option

 

Enable or disable internal threading on the mounting pillars to accommodate screws directly or use smooth pillars for press-fit or alternative fastening methods.
