T-Slot 8040 Dual 4040 Corner Connector (L-Shape)
Print Profile(1)
Description
This is a double-height external L-shape corner connector for 40×40 T-slot aluminum profiles, designed to provide a stronger and more stable joint than the standard single connector.
Perfect for building rigid frames, enclosures, CNC or printer bases, and other heavy-duty modular structures.
Features:
🧱 Dual-layer design — fits two 4040 profiles stacked vertically (or one 8040)
🔩 Friction-fit connection — holds firmly in the T-slot grooves without screws
⚙ Precise, rounded geometry for consistent fit across T-slot brands (Bosch, Item, Motedis, etc.)
🖨 Prints flat on the bed, no supports needed
🔧 Ideal for strong right-angle structural joints and modular extensions
Tolerances are tuned for a snug fit on standard 4040 profiles. If needed, adjust ±0.1–0.2 mm for brand-specific extrusions.
