What is this?
These 3D printer die springs are designed to provide consistent performance in most 3D printer heated beds, as well as automobiles, electrical appliances, instruments, and more industrial applications.

What will I get?
3D Printer Heating Bed Spring,
Material: 65Mn steel;
Inner dia.: 4mm/0.16in;
Outer dia.: 8mm/0.31in;
Height: 25mm/0.98in;
Compression ratio: 0.24;
Color: Brown;
In the package of: 8 pcs.

Is there any advantages of the product?
Fine material: Our die springs are made of 65Mn steel with a painted surface, which is wear-resistant, sturdy, durable, not easy to break, and harder than ordinary springs, which helps to stabilize printing.
More tension and stability: Our die spring makes you avoid the need to level the bed before each print, providing more tension and stability, and making bed leveling more precise and firm.

How to use it?
Use a compressor to compress the spring to the length suitable for installation, then place the spring at the installation position, and secure it with screws, nuts, and other tools. Finally, slowly release the compressor.

What should I notice?
Confirm the spring dimensions are suitable for your 3D printer model before installation. Avoid compressing the springs beyond their designed capacity, as this may affect performance.
