Aluminum Profile 20×40 V-Slot Black

Product Description :

The Aluminum Profile 20×40 V-Slot-Type Groove 6 is a strong, lightweight, and versatile extrusion designed for 3D printers, CNC machines, laser engravers, and modular DIY projects. Made from high-quality aluminum with a black anodized finish, it combines rigidity with corrosion resistance for long-term use.

With a 20x40mm cross-section and 6mm groove width, this profile is compatible with a wide range of M5 fasteners, nuts, and standard V-slot accessories. The inner core supports M5 threading, making it easy to build solid frame connections. Weighing only 0.622kg per meter, it offers an excellent balance between strength and low weight, ensuring stable motion without adding unnecessary bulk.

The V-slot design allows smooth movement with V-slot wheels, eliminating the need for extra guide rails. This makes the 20×40 aluminum extrusion perfect for precision motion systems such as CoreXY printers, Voron builds, CNC routers, and robotics frames.
