1、EFFICIENT HEAT DISSIPATION: The extrusion head heat dissipation and cooling kit ensures efficient heat dissipation, preventing overheating during long printing sessions. 2、PERFECT COMPATIBILITY: Extruder fan 3 duct extruder head cooling kit, compatible for Bamboo P1P X1 3D printer. 3、PREMIUM MATERIAL: The magnetic printing cooling fan duct is made of PA12 material, high temperature resistance, high toughness, not afraid of high temperature attack on the print head. 4、THREE AIR DUCTS: Replacing two air ducts with three air ducts surrounded by three sides allows the air ducts to dissipate heat more accurately and perform multi side cooling to improve the cooling effect. 5、CAUTIONS: In order to avoid the magnetic inconsistency of individual machines, the magnet is not directly installed, the magnet needs to be confirmed and the magnet on the extrusion head housing attract each other before installation to avoid magnetic repulsion.
