Key Applications & Projects

• 3D Printer Frames: The standard for Voron, Hypercube, and other high-end DIY printers.

• CNC Machine Cages: Provides the structural rigidity needed for hobbyist milling machines.

• Laboratory Racks: Clean, professional-looking joints for equipment mounting.

• Modular Furniture: Build sleek, modern desk frames or shelving units.

Unlock New Capabilities (Project Evolution)

• Past Projects (Prerequisites): If you've been using 2-way corner brackets and flat plates, you've likely struggled with "parallelogramming" (the frame skewing out of square).

• Feature Upgrade: This 3-way connector acts as a Structural Datum. It locks three profiles together in a perfect orthogonal cube, automatically squaring your frame without the need for a carpenter's square.

• Effort/Requirements: Beginner-friendly. Only requires a 2mm/2.5mm Allen key.

Virtual Technician & Assembly

• Safety Tip: Ensure your aluminum profile ends are cut "square" (90 degrees) for the tightest possible joint.

• Assembly Step 1: Slide the three profiles into the three arms of the cube connector.

• Assembly Step 2: Tighten the included grub screws through the profile slots into the connector shoulders.

• Assembly Step 3: (Optional) Snap on a corner cap for a professional, dust-proof finish.

Accessories

• Included: 1x 3-Way 2020L Cube Connector, 4x Grub Screws.

• Required Additional: Allen Key, 2020 Aluminum Profiles.

Frequently Asked Questions (FAQ)

1. Does this kit include the profile caps? This specific SKU includes the connector and screws; caps are sold separately.

2. Will it fit 2040 profiles? Yes, it fits the 20mm face of 2040 profiles.

3. What size Allen key is required? Typically a 2mm or 2.5mm hex key for the grub screws.

4. Is this stronger than cast corner brackets? Yes, it creates a much more rigid 3D joint by locking all three axes.

5. Can I use this for 3030 profiles? No, this is for 20mm series profiles only.

6. Is it compatible with V-Slot? Yes, it is fully compatible with 2020 V-Slot extrusions.

7. Is the finish matte or shiny? It has a professional sandblasted matte silver finish.

8. Do I need to tap the holes? No, the screws tighten against the profile slot; no tapping is required.

9. How many screws are included? We include 4 screws per connector to ensure a secure lock.

10. Can it be used for heavy-duty tables? For heavy workstations, we recommend using these in conjunction with external reinforcement brackets.

11. Is it rust-proof? Yes, the zinc alloy is naturally corrosion-resistant.

12. Can I use this on black profiles? Yes, the silver finish provides a nice technical contrast, or it can be painted.

13. What is the weight? Approximately 35 grams.

14. Is it "L-type" or "T-type"? It is an L-type 3-way corner (forming a 90-degree corner).

15. Does the profile need to be drilled? No drilling is necessary.

16. How do I ensure the joint is square? Simply push the profiles flush against the connector shoulders before tightening.

17. Can I reuse these? Yes, they are easily removable and reusable for new designs.

18. What is the thread size of the grub screws? Standard Metric M5 (or M4 depending on the batch revision).

19. Will this fit 1515 profiles? No, only 20mm profiles.

20. Does Probots offer 3D models? Dimensions are provided; CAD files can be requested for large projects.
