3D printing enthusiasts, these MroMax die springs are a handy upgrade for your printer's bed leveling or other mechanical needs. You get two blue steel compression springs, each with an outer diameter of 0.47 inches (12mm), inner diameter of 0.24 inches (6mm), and a free length of about 2.95 inches (75mm). They're designed as light load springs, made from durable spring steel with a blue painted finish to resist rust. These springs are commonly used in injection molding dies, but they work great for 3D printers where consistent tension and compression are key. They have a maximum compression ratio of 0.4 and can handle high-stress applications.
