Universal Heatsink for V6 Hotends

This aluminium-alloy heatsink fits V6-style hotends on printers such as the Prusa i3 MK3 and J-Head Bowden extruders. It accepts both 1.75 mm and 3.00 mm filament paths. The black finish matches common hotend assemblies. It is supplied as a single component ready for installation.

Check Thread Sizes and Clearance

Verify that your hotend uses an M10 top thread and an M7 bottom thread before ordering. The overall diameter is 22.3 mm and the height is 43 mm, so confirm there is enough space around the heater block and fan shroud. The top outer diameter measures 16 mm. No other mounting hardware is included.

Integrates With Standard V6 Cooling

The heatsink threads directly between the heatbreak and the cooling fan, dissipating heat from the melt zone. Its aluminium construction transfers thermal energy quickly, helping to maintain a sharp temperature transition. The compact 22.3 x 43 mm profile leaves room for surrounding ducting or enclosure panels. It replaces a worn or damaged original without modifying the extruder geometry.
