Universal PCB Enclosure (Fully Parametric)

🚀 Overview

Stop wasting filament on enclosures where the USB ports don't line up! This Ultimate Parametric Project Box is specifically engineered to solve the "Mirror Trap." Most DIY boxes fail because when you flip the lid, the cutouts move to the opposite side. This model uses Automatic Mirror Logic to ensure your USB and cable ports align perfectly every single time.

🛠️ Key Features

• Perfect Alignment: Advanced OpenSCAD logic mirrors the top half automatically. If your USB is on the left in the base, it stays on the left when closed!
• 100% Support-Free: All cutouts (USB, Cables) and joints are designed to print perfectly without any support material.
• Fully Parametric: Easily adjust length, width, height, and wall thickness to fit your specific PCB or project.
• Electronics Ready: Includes dedicated settings for PCB Pillars (default 16mm for stacked plates), Ventilation Grills (essential for ESP32/WiFi), and Cable Cutouts.
• Secure Snap-Fit: Features a precise male/female joint with a 0.2mm clearance for a firm, satisfying click-close.

📐 Default Dimensions (Optimized for every custom pcb)

• Internal: 75mm x 52mm x 20mm
• Pillars: 16.0mm height (Perfect for under-bed relay controllers)
• Wall Thickness: 2.5mm for maximum durability.

🖨️ Print Settings

• Material: PLA, PETG, or ABS/ASA (recommended for high-heat electronics).
• Supports: NONE.
• Orientation: Both halves are pre-positioned flat on the bed.
• Infill: 15-20% Gyroid for strength.

💡 Pro Tip for OpenSCAD Users

If you are customizing the code, simply change the pcb_offset_x or usb_side variables. The Mirror Logic in the render block will handle the rest, ensuring your top and bottom halves remain synchronized.
