 🚪 81.5mm Heavy Duty Butt Hinge

A strong, highly precise, and functional 3D-printable butt hinge designed for cabinets, small doors, workshop boxes, and everyday DIY repair projects.

📏 Specifications :

• Dimensions: 51mm (W) x 81.5mm (L) x 10mm (H)
• Design: 6 Countersunk screw holes for a flush, professional finish.

🖨️ Recommended Print Settings:
For maximum strength and durability, please use the following slicer settings:

• Filament: PLA+, PETG, or ABS (White PLA looks excellent!)
• Layer Height: 0.16mm or 0.20mm High Quality
• Wall Loops / Perimeters: Minimum 4 (Crucial for the hinge knuckles' strength)
• Top/Bottom Shell Layers: 4 to 5
• Infill: 25% - 40% (Gyroid or Cubic recommended)
• Supports: No supports needed if printed flat. 
• Brim: Outer brim recommended if you have adhesion issues, though not strictly necessary on a clean PEI plate.

🛠️ Assembly:
Requires a standard metal pin (if not printing the pin) and 6 standard countersunk screws. Ensure your printer is well-calibrated so the hinge leaves interlock smoothly!
