We are renaming the Bondtech LGX For Flexibles.
New name is LGX Shortcut. This version is now called LGX Shortcut Copperhead.

Each LGX Shortcut Copperhead Hotend is supplied with:

  • 1x LGX Black Anodized Aluminum Heat Sink
  • 1x LGX Black Anodized Aluminum Air Cooled Cold Block
  • 1x LGX Air-cooled Cold Block Mounting Hardware
  • 1x Copperhead LGX Heat Break
  • 1x Copperhead Hot Block
  • 1x Bondtech M6x1x7.5 Coated Brass Nozzle 0.4mm
  • 1x Silver Based Thermal Paste Sachet 0.5g


Designed To Be Flexible

The LGX Shortcut Copperhead Hotend includes a reversible heat sink that can be installed on the left or right hand side of the cold block. The heat sink also includes the hole pattern for attaching 40×40 fans.

Cooling down the heat break

Our tests suggest a 4010 fan is enough to cool down the cold block and the cold zone of the heat break, even with such small contact surface to the heat sink.

In case you have an application where additional cooling is required, try using a 4020 fan or 2 LGX heat sinks, one on each side.

Main Advantages

  • Gives access to softer materials.
