The LGX Shortcut only supports 1.75 mm filament.

Designed To Be Flexible

The Bondtech LGX™ Shortcut 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 a hole pattern for attaching 40×40 fans.

Cooling down the heat break

Bondtech's tests suggest a 4010 fan is enough to cool down the cold block and the cold zone of the heat break, even with such a 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.

Compatible nozzles

The hot block included in this product is compatible with Rep Rap style nozzles, such as:

• BridgeMaster Nozzles (for peak bridging performance) 
• Vanadium Nozzles (for abrasive applications)
