Phaetus Heat break for water-cooled hot-end ST

The Phaetus Heat Break for water-cooled hot-ends (ST) is a precision spare part that improves thermal isolation between the heater block and the heat sink. Designed for ST-type water-cooled assemblies, it reduces heat creep, stabilizes extrusion temperatures, and ensures reliable filament flow during demanding prints.
