Here are the simplified titles: 1. MK8 Hot End Extruder Nozzle Kit 0.4mm for 3D Printer 2. Assembled Extruder Brass Kits 1.75mm 3. 30mm A8 Throat Tubing Aluminum Heater Block for RapRep i3 Anet A2 A8 3D Printer Part Replacement

This DIY replacement kit is specially designed for the Anet A2 & A8 3D printers. It includes a pre-wired thermistor, a 12V 40W cartridge heater, an aluminum heater block, and a 0.4mm output nozzle.

The thermistor is a NTC3950 model with a resistance of 100K ohms at 25°C and a cable length of approximately 1.1m. It can withstand temperatures ranging from -40°C to +300°C.

The extruder throat is made of stainless steel, with an input diameter of 1.75mm, a length of 30mm, and an external thread diameter of 6mm, suitable for 1.75mm filament.

The nozzle is a brass 0.4mm model, compatible with 1.75mm and 3mm filaments, including PLA and ABS.

The heater is a high-temperature, stainless steel, 12V 40W cartridge heater.

The package includes: - 1 x 0.4mm MK8 extruder nozzle - 1 x 30mm throat tube - 1 x heater block - 1 x thermistor - 1 x cartridge heater - 1 x wrench

The heated tubing is a 12V/40W high-temperature resistance heater with a wire length of 1m (39.4 inches) and an operating temperature range of 0°C to +280°C (0°F to +538°F).

The 0.4mm extruder brass nozzle is compatible with 1.75mm PLA and ABS 3D printers.

The 30mm length extruder tube, made of stainless steel, is compatible with 1.75mm PLA and ABS 3D printers. It helps reduce extrusion force and improve the reliability of retractions thanks to its improved internal surface finish.

The aluminum heater block, measuring 2cm x 2cm x 1cm, works perfectly with ABS and PLA filaments and comes with a necessary M6 screw.

This kit allows you to repair your extruder instead of replacing the entire unit when your extruder suffers a clog that cannot be fixed. It is a great replacement hot end for MK8, i3, E3D, Anet A8, Alunar M508, CR7, V2, and other 3D printers.
