About the Product
A black silicone insulation cover sized 23×23×17.5mm with a 1.5mm wall thickness, designed to wrap the heater block on FDM 3D printer hotends. The cover reduces heat loss, stabilises hotend temperature, and protects surrounding components from radiant heat. Suitable for standard MK8/MK10-style heater blocks commonly found on Creality Ender and CR series printers.
