High compatibility with multiple ports and mounting holes

The Hermit Crab hotend and tool changing system simplifies assembly and use of multiple tool heads on your 3D printer with a linear or V-slot rail.

The basic version of the Hermit Crab requires that all cable connections be reconnected to the motherboard and is supplied with 1 tool plate. The basic Hermit Crab works with any firmware.

With different mounting hole patterns and connections on the face of the tool changer, various extruders, like the E3D Hemera**, Bondtech DDX**, LDO Orbiter**, and Bowden style hotends can be attached. Includes interfaces for extra functions, like filament sensors, levelling sensors, stepper motors, and fans.

**extra components or printed parts may be required

In addition to printheads, various other tools can also be mounted. This way, your printer can be a laser engraver/cutter, pen plotter, as well as other useful devices easily.

Components Supported:

  • 1 x Stepper motor
  • 1 x Filament sensor
  • 1 x Heater 
  • 1 x Thermistor
  • 2 x Fans

Quick tool change for efficient work

Changing tools only requires a single movement. 

The fixed plate of the Hermit Crab remains connected to the rails then the tool plate with the printhead/ tool mounted simply attaches and stays fixed with a spring clip.

Better print quality

The tool change system makes smoother motion and higher precision and printing performance possible on your machine. Further gains can be made with a MGN12 Linear Rails System


The hotend and tool change system consists of a durable 6061 aluminum alloy and guarantees long-lasting quality.
