ELEGOO3D Printer Extruder for Neptune 3 Pro/3 Plus/3 Max 3D Printer, Fully Assemble Dual-Gear Direct Drive Extruder, ELEGOO Official 3D Printer Accessories

Easy to install. I installed it in 10 minutes. It fits exactly as the original factory parts do. As for the comments about the holes not lining up, you need to start all 5 mounting screws, 3 long ones in the back, then the 2 infront, and then go back and tighten them all up. The part works just fine. Same print quality as my first print when I bought the printer. I reprinted the test Budda from elegoo and compared them.

Exelente producto viene con su tornillería,fue simplemente montar y ya una acción de 10 minutos

Didn't know how bad my other printer head was till I replaced it. Game changing difference.

Buying this additional extruder unit was so worth the money! With the amount of time it takes to change a nozzle or a fan, you can keep your work going by simply popping in a new extruder unit. Then you can take your time refurbishing the one you removed without impacting your productivity. 5 screws and around 5 minutes to get you back up and running. Brilliant!

They work great

Perfect replacement for the oem head. Works like the original.

This is the complete head assemblyIt is everything including the level sensor and new screws to attach it to the rail.I am very pleased with the unit received.

We had major issues with both the sensor probe and with the extruder assembly lock for the filament. The gears that are supposed to grab the filament and move it through the system on this replacement, which we purchased direct from the ELEGOO store, were plastic instead of the metal ones found on the OEM part that came with our original Neptune. We needed to replace the assembly because of some issues we had with the old part when replacing the nozzle. We'd had it for a little over a year, and the screws holding the throat and heat assembly snapped inside of their drill holes, which prompted us to purchase this new one. Thankfully we kept the old part in case there were issues with the new one and were able to swap out the plastic gears for the metal ones in our old part, as the gears for that bit weren't what was damaged. But shame on ELEGOO for putting plastic gears in that couldn't hold the filament and caused print fail after print fail. It might be a cost saving measure, but it came at the expense of a customer.
