🔧 Corner Connector for 20x20 mm Aluminum Profiles – With 8mm Panel Mounts – Perfect for Building 3D Printer Enclosures

Looking for a simple and sturdy way to connect 20x20 mm aluminum profiles and mount enclosure panels? This corner connector does both in one smart design!

🛠️ Print Settings & Tips:

• Material: PETG (e.g., Sunlu) – for durability and temperature resistance,
• Infill: 30%, tree supports (only touching the build plate),
• Walls: 4 perimeters for extra strength,
• Supports: Auto-generated, tree type, base only,
• Cooling: As needed for PETG (moderate fan),
• Orientation: Best printed in a way that maximizes strength along the axis of the connected profiles.

🧩 Key Features:

• Designed to fit standard 20x20 mm aluminum extrusion profiles (with 16x16 mm inner opening),
• Includes built-in slots to mount 8 mm thick panels – perfect for creating a fully enclosed 3D printer chamber,
• Makes it easy to build modular frames, cabinets, walls, or enclosures,
• Tested in real-life use – used to build a custom enclosure for the Bambu Lab A1.

🎯 Who is it for? Perfect for makers, DIY enthusiasts, and 3D printing fans who want to:

• Build an enclosed chamber for heat-sensitive prints,
• Organize their workshop with lightweight aluminum structures,
• Or simply create custom furniture, frames, or setups with full flexibility.
