Good but Tight Fit

Quality is good and prints look sharp. Had to apply a bit of force to fit it onto the carriage but once installed it works perfectly.

Perfect for High Temp Materials

I print a lot of ABS and ASA. This hotend handles the higher temperatures without any issues. The hardened nozzle is a must have for durability.

Solid Build Quality

The aluminum block heats up evenly and the temperature stability is great. Happy to see compatibility options for other mounts as well.

Excellent Upgrade for Kobra 3

Installation was straightforward and the hardened steel nozzle handles abrasive filaments much better than the stock brass one. Print quality improved noticeably.
