Thermal Bed Support Kit for 3D Printers – 4 Pieces

With this M3×40mm heat bed leveling kit, secure and repeatable adjustment of heated bed positions is achieved across various 3D printer models. Each set includes a durable compression spring engineered for 20mm height and 1.2mm wire diameter, ensuring optimal tension without compromising bed stability. Accompanied by matching screws and hex nuts, the kit provides strong mechanical support to maintain accurate Z-axis offsets and minimize vibration across long print runs. Sold as a 4-piece set for standard four-corner heated bed platforms.
