Strength meets modularity. Our 2040 V-Slot Aluminum Profile is the industrial standard for building rigid, high-speed 3D printers and DIY CNC machines. In a My-CoreXY build, the 2040 profile is strategically used in the frame and gantry to minimize flex, ensuring that your prints remain accurate even at extreme accelerations.
Unlike standard T-Slot, the V-Slot profile features a unique beveled edge on all internal slots. This allows it to double as a linear rail when used with V-Wheels, providing a cost-effective yet incredibly smooth motion system. The 20x40mm cross-section provides the necessary moment of inertia to prevent sagging on wide machines, making it the primary structural element for any professional Open Source Fabrication project.
Why 2040 V-Slot is essential for your My Machines project:
-
High Load Capacity: Perfect for the vertical pillars and the main Y-axis rails of the My-CoreXY.
-
Modular Fastening: Compatible with all M3, M4, and M5 T-Nuts, allowing for easy mounting of electronics and brackets.
-
Precision Extrusion: 6063-T5 aluminum alloy ensures straightness and dimensional consistency.
-
Industrial Look: The deep black anodized finish is not just for looks; it provides a hard surface that resists scratches from T-nuts and brackets.

Consultant’s Pro-Tip: When designing your My-CoreXY gantry, use the 2040 profile on its edge (vertically) to maximize resistance against bending. For a professional finish, we recommend using a 90-degree Corner Bracket combined with M5 Low Profile Screws. Always check for squareness during assembly—a perfectly square frame is the secret to a machine that prints fast without artifacts.
