Vyper/I3 Mega Heatbreak,Kobra 2 Heatbreak,Upgrade Titanium Alloy Bi-Metal for Kobra Max/Kobra 2/Neo/Kobra 2 Pro/Plus/Max/i3 Mega/Mega S/X/Pro/Vyper/Chiron Hotend.(2PCS)

These work well when installed properly. They did not come with instructions (so I gave 4 stars), so if you aren’t sure, just watch some YouTube and go slowly. Once installed they help keep the heat at the hit end where it should be and reduce clogs, which will improve print quality.

Solid heatbreak for Anycubic Kobra/Vyper printers. The titanium alloy bi-metal design improves heat resistance and noticeably reduced clogs on more problem prone prints for us. It's not priced outlandishly which means you're not out much if you'd to try it yourself

The heartbreak fits well. I like that it is composed of 2 different materials. The copper has a higher thermal conductivity to keep the filament cool and the Titanium provides better thermal isolation from the heater. The section with flats on it for tightening the extruder to the heat block requires a very thin wrench. It would be nice if the gap between this tightening piece and the bottom of the copper tube were about 2mm wider. The quality and machining of the extruder is very well done.
