Description
This is a snap-fit side connector designed for 20x20 V-slot aluminum extrusion profiles.
It allows you to connect two profiles side-by-side to create wider structural beams such as 2040, 2060, 2080, or any custom combination.
The model is printed flat on the bed, at 12 mm height in Z-axis by default
To create a longer connector, simply scale the Z-axis in your slicer
No need to edit the 3D model – just change the height to your desired connector length (e.g. 20 mm, 40 mm, 60 mm)
Fits into two adjacent V-slot channels
No screws or hardware required
Provides strong side-by-side alignment
Modular – print multiple connectors to increase strength
Perfect for building wide gantries, reinforced beams, or custom machine frames
Orientation: Print flat (default orientation)
Scale: Adjust Z-axis for desired connector length
Material: PLA, PETG, ABS (PETG recommended for strength)
Layer Height: 0.2 mm
Infill: 40–100% (depending on required strength)
Supports: Not needed
Designed for V-Slot 2020
Works with OpenBuilds and all standard 20 × 20 aluminum extrusion profiles
CNC frames
3D printer upgrades
Laser engravers
Modular robotics
Custom structural builds
