SKU CH-KWN6-GXDVA

Aluminium-alloy V6 heatsinks with M10 and M7 threads cool 1.75 mm and 3.00 mm hotends, supplied in a pack of three

  • Cools 1.75 mm and 3.00 mm filament paths
  • M10 top and M7 bottom threads fit V6 hotends
  • Black aluminium alloy dissipates heat efficiently
  • Three heatsinks included for multi-printer setups
  • 3 mm diameter by 43 mm height fits standard mounts

Compatible Heatsink for 1.75mm and 3.00mm Filament

This aluminium-alloy heatsink fits both 1.75mm and 3.00mm filament paths on V6-style hotends. It threads onto M10 at the top and M7 at the bottom. The pack contains three black units for spares or multi-extruder setups.

Check Hotend Threads and Filament Size

Verify that your existing hotend uses M10 top and M7 bottom threads before ordering. Confirm the filament diameter matches 1.75mm or 3.00mm specifications. Ensure the 22.3 mm outer diameter and 43 mm height clear surrounding parts on your printer carriage.

Mounts on V6 Prusa i3 MK3 J-Head Bowden Extruders

The heatsink installs directly onto compatible V6 heatbreaks used in Prusa i3 MK3 and J-Head Bowden designs. Its 16 mm top outer diameter seats into standard cooling blocks. Aluminium construction dissipates heat without adding a separate fan mount, leaving fan choice open.
