The Copperhead Heat Sink is one section of the The Copperhead hotend range The full range can be found here. 

PLEASE NOTE: The Copperhead Heat Sink is only compatible with the Copperhead Standard Heat Break because our Copperhead Heat Sink uses a shank and collar mechanism (no threading) to hold onto the heat break.

Compatibility Screw Mount:

• Bondtech DDX
• Mounting interface using a 12mm hole pattern with 4x M2.5x0.45 tapped holes. (similar to the Mosquito™ mounting interface)

Compatibility Groove Mount:

• Bondtech BMG
• Bondtech QR
• D-Bot Core XY
• Formbot Raptor 1 & 2 & Troodon
• G Create GMax 2 Pro
• RailCore II
• Zesty Nimble
• Any freestanding Groove Mount Hotend

The Copperhead is a low-cost, open-source hotend option that can handle the heat — heat creep, that is. Replace your factory model hotend with the Copperhead™, to upgrade your 3D printer’s performance and reduce jamming, giving you a smooth print every time.

Unlike most materials, plastics don’t have a clean transition from solid to liquid during melting. As filament moves through the hotend, it heats up and reaches the material’s glass transition temperature (Tg), entering a semi-solid, semi-liquid, “gooey” state. While in this state, the plastic responds to applied forces like a wet noodle, causing undesirable print effects like reduction in resolution, blobbing and jamming. An efficient heat break narrows the physical distance during which the plastic is at it’s Tg, and thus improves 3D printer performance. The Bimetallic Heat Break™ from Slice Engineering® is the only heat break designed through the use of thermal imaging to optimize heat transfer.

We highly recommend the use of BN paste with the Copperhead to provide good thermal conductivity between the hot block and heater/thermistor.
