Conch Hotend™ M4-A1-Serie

It is definitely an upgrade from the stock nozzle. Very much worth it. Just don't forget to thighten it before using

Everything arrived ahead of schedule, corresponds to the description. one additional 0.4 mm nozzle was in the hotend itself, so in total I got 5 nozzles.

I’m still relatively new to 3D printing, and only just recently began working with materials other than simple PLA. I put this hardened hot end to work with some wooden filament, and I’m generally pleased with the results. While still trying to dial in greater precision, the nozzle has been performing as well as any OEM hot end I’ve owned previously. A slight variation in the design style of the cooling fins is really the only physical difference compared to the OEM, with installation and removal remaining the same. The replaceable nozzle arrived loose but tightened easily. I’ve no experience with replaceable nozzles and how to swap them when the filament has cooled, but having the option to swap sizes using the same hot end may lead to some cost savings.
