By using this strong spring steel compression coil, stable mounting and leveling of heatbeds or structural assemblies is achieved across 3D printers and CNC platforms. Manufactured with precision winding and hardened steel, the spring resists deformation under continuous load while maintaining consistent tension. With a 20mm height, 9 coil turns, and sizing optimized for M3 mounting systems, it’s suited for high-frequency Z-axis travel, heated bed support, and vibration buffering applications.
