4x7x4mm Aluminum Isolation Column Spacer for 3D Printer

The 4x7x4mm Aluminum Isolation Column Spacer is a high-precision mechanical component designed specifically for 3D printer V-wheel pulley assemblies and carriage plates. It provides precise spacing and isolation, ensuring that your guide wheels run smoothly along the aluminum extrusions without any wobble or binding. CNC machined from high-grade aluminum, this spacer offers excellent structural integrity and corrosion resistance while keeping the overall weight of your moving carriage to an absolute minimum.

This aluminum spacer features a 4mm inner diameter, making it perfectly compatible with standard M4 screws and bolts commonly used in 3D printer builds. It is widely used in popular desktop 3D printers such as the Creality Ender 3, CR-10, and various DIY CNC machines. Whether you are building a custom coreXY motion system or replacing worn-out spacers on your existing machine, this isolation column ensures accurate alignment and improved print quality.

Features:

• High-Quality Aluminum: CNC machined from lightweight and durable aluminum alloy for long-lasting performance.
• Precise Dimensions: Features a 4mm inner diameter, 7mm outer diameter, and 4mm height for exact spacing.
• V-Wheel Compatibility: Perfect for spacing out V-slot guide wheels and pulleys on 3D printer axes.
• Smooth Operation: Eliminates play and wobble in the carriage assembly, improving print quality.
• Lightweight Design: Weighs only 0.3 grams, minimizing the moving mass of the print head or bed.
