2040 V-slot extrusion for modular frames and linear motion systems

The 2040 V-Slot Extrusion (20 Series) is a 20mm x 40mm x 2.5m black aluminum profile built for strong, lightweight, and modular constructions. It is well suited to 3D printers, CNC machines, laser engravers, and automation projects where frame rigidity and clean assembly matter.

The V-slot profile also supports smooth linear motion in wheel-guided systems. For custom mechanical builds, the 2040 format combines modular flexibility, precision, and durability in one structural component.

Key features of the 2040 V-slot extrusion

• 6063-T5 aluminum construction: High-strength 6063-T5 aluminum provides durability while keeping the profile lightweight.
• Black anodized finish: The anodized surface improves corrosion resistance and gives the extrusion a professional appearance.
• V-slot profile for guided motion: The V-slot design enables smooth linear motion when used with V-slot wheels, making the extrusion suitable for precision movement assemblies.
• 20mm x 40mm rigid format: The 2040 shape offers improved structural stability for medium- to heavy-load applications.
• Pre-drilled centre core: The centre core allows easy tapping for M5 screws, which helps simplify fastening and frame construction.
• Modular build flexibility: The 20 Series format supports clean assembly, reconfiguration, and expansion in custom machine and workshop projects.

Where to use 2040 V-slot extrusion in DIY and engineering projects

3D printer and CNC machine frames

The 2040 profile provides a strong, lightweight, and stable structure for machine frames. Its added rigidity compared with narrower profiles makes it useful where better support is needed across longer spans or heavier assemblies.

Linear motion systems with V-slot wheels

This aluminum extrusion is ideal for V-slot wheel-based setups that need smooth guided travel. The profile can be used in axes, gantries, sliders, and other precision movement assemblies.

DIY robotics and automation builds

The 20 Series extrusion works well for machine frames, workbenches, enclosures, and custom automation structures. Its modular format helps simplify prototyping, expansion, and reconfiguration as a project changes.
