OpenBuilds black 90° angle corner connector for 20mm V-Slot and T-slot frames. Milled aluminum corner hardware for squaring and reinforcing extrusion joints on CNC, laser, and 3D-printer frame builds.
Why use this connector
- 90° frame joints: made for attaching accessories or joining extrusion at a right angle.
- 20mm extrusion fit: documented for 20mm V-Slot or T-slot profile systems.
- Black anodized aluminum: a compact metal bracket that blends into black OpenBuilds-style frames.
- Dual-use geometry: commonly used as a corner connector and, where the build calls for it, an adjustable wheel block.
Specifications
- Part: OpenBuilds Black Angle Corner Connector
- Angle: 90°
- Material/finish: milled aluminum, black anodized
- Extrusion compatibility: 20mm V-Slot / T-slot profile systems
- Typical mounting hardware: M5 × 8mm low-profile screws with M5 T-nuts; hardware is not included unless your order explicitly says otherwise.
Fitment and pairings
- Use with 2020 extrusion for small machine frames, fixtures, enclosures, and accessory mounts.
- Pair with Hammerhead T-Nuts for 20 Series Aluminium Extrusion when you need drop-in fastening on a 20-series slot.
Gotchas
- This is a single connector, not a multi-pack.
- This is for 20mm-series extrusion systems; do not buy it for 15-series MakerBeam or 30-series extrusion unless your build documentation specifically calls it out.
- It does not replace a full structural plate where your design needs high-rigidity gantry or load-bearing reinforcement.
