Titanium V6 heatbreak V2.0 by 3D passion (1.75mm, All-Metal, Our in-House New Design), 2-Pack.

It is my own heatbreak design. 2x better thermal barrier performance vs E3D heatbreak. It is not a clone, geometry is different - see second photo for details. I reworked geometry and improved tolerances and features. Search terms: V6 heatbreak, E3D V6 Heatbreak, V6 Titanium Hetbreak, V6 hotend titanium throat.
