BondTech LGX Shortcut Mosquito for Prusa MK3S

This is an LGX Shortcut Upgrade Kit for use on the Prusa MK3S and MK3S+. It uses a short Mosquito hotend from Slice Engineering with a Bondtech heatsink.

Requires an X-Carriage

To use the LGX Shortcut Upgrade Kit, you need the appropriate X-Carriage.

You can buy it here or download and print the X-Carriage model.

Master all materials

The LGX Shortcut Mosquito printhead is a special unit that includes the LGX Large Gears Extruder and the LGX Shortcut Hotend with a short filament path based on Copperhead, which masters all materials. The print head is therefore the perfect choice for processing soft and flexible materials.

The LGX Shortcut Mosquito Printhead only supports 1.75mm filament.

Direct Drive upgrade

This LGX based upgrade kit is an easy to install replacement for the stock direct drive extruder. It requires the accessory included in the " LGX Shortcut Mosquito Accessories for Prusa MK3S " package and the LGX Shortcut Mosquito Hotend

Easy to install

It's a very intuitive and easy to install upgrade kit where the extruder faces the X-Carriage, reducing the distance between the nozzle and the X-axis.

Leading Grip Power

The LGX is the Bondtech extruder with the highest filament grip due to its new large drive wheels that allow more teeth to engage the filament.

MMU compatibility

This upgrade kit is not compatible with any MMU version.
