This is the official Creality 3D Hotend Sock and sticker pack. The newesttrend in 3D printing, hotend socks, help to keep hotend temperatures fromfluctuating and therefore improving print quality. We have developed a high-temperature silicone sock designed to work well with all Creality 3D printers.Use this sock to help manage hotend temperature while cooling fans operate athigh speeds cooling filaments that require a much higher extrusiontemperature. This hotend sock will improve success rates on prints with thesetypes of exotic filaments as well as reduce effects of heat radiation from thehotend onto smaller models which might be more sensitive to such heatfluctuations.
