LDO Jabberwocky Toolhead & Extruder
Toolhead and Extruder designed for filament changers
The LDO Jabberwocky is designed for high-performance filament changing systems. It handles the stress of FCUs with ease. Thanks to its robust construction, it offers both reliability and precision.
The extruder uses a Bondtech compound gear in an offset layout. It also features dual LDO non-threaded Orbiter gears. This combination improves grip and control. As a result, filament stays stable during loading and unloading.
Moreover, the system balances torque and speed. It ensures smooth operation under heavy loads. Maintenance is also simple. The tool-free hinged extruder allows quick access without tools.
To enhance cooling, it includes high static pressure fans. These fans direct airflow exactly where needed. Additionally, the Phaetus Conch hotend delivers high flow with low clogging. It supports up to 35 mm³/s, making it ideal for fast, clean extrusion.
Key Features:
- Designed for FCUs and multi-material changers
- Bondtech compound gear in offset configuration
- Dual LDO Orbiter gears for better filament grip
- Balanced torque and speed for smooth operation
- Tool-free hinged extruder for easy maintenance
- High static pressure fans for targeted cooling
- Phaetus Conch hotend with 35 mm³/s flow rate
Variants:
The Jabberwocky is available in three variants:
- Prebuilt Jabberwocky Kit – This is fully assembled at the LDO facility and ready to install in your printer (after you print the correct mounting plate for your printer). It is intended to save time or for less effort.
- Standard Jabberwocky Kit – Also sometimes referred to as DIY or Unassembled. This is the recommended kit for beginners to advanced users. Visit this Wiki link for instructions.
- Basic Jabberwocky Kit – This is intended for open development or advanced users who want to use different toolheads and different electronics. Examples like UHF Rapido or Revo toolheads are being actively developed/tested. Visit the discord channel to find out what third-party or independent users have created for the Basic Jabberwocky Kits.

What a great toolhead kit! While still being developed with a very active discord group the Jabberwocky actually performs very well.
I am testing this on a Voron Trident purely on PLA at the moment and have had no print quality issues so far in the 30 hours of print time.
Around 80g lighter overall then the StealthBurner filamatrex version, there is less mass to move about resulting in better accelerations.
Have not yet used it for MMU/AFC cutting but there are some component reprints to accomplish to bring in the latest iterations.
This is an early adopter product currently and will require some reprinting of the printed parts as more people adopt and give feedback but, overall, it performs very well even at this early stage of release.
Overall, great value for money!
