3D model description

This project is fully open source, so you can easily adapt it to your needs.
I used the Orbiter extruder because I really like this design and large gears for precise filament feeding. I also like Dragon hotend from DFORCE Trianglelab because it is relatively inexpensive, provides good functionality, has a fixed screw mounting and allows you to change the nozzle with one hand.
Using a different extruder (Sherpa Mini or BMG with pancake motor) or hotend (E3D V6 or Dragonfly BMO) should not be difficult with this design. You need to slightly modify the parts with your CAD software.

The project was created for the purposes of modifying and improving my 3D printers.
The original Two Trees hotend poses a lot of problems for users and does not allow print materials at higher temperatures, because the PTFE tube touches the nozzle. This can often lead to slack in the bowden setup and ultimately the formation of jams and clogs.
The use of a lightweight direct drive extruder and one of the best hotends allows you to ensure printer reliability, improve print quality and enable printing of materials that require higher temperatures.

The use of printed parts and a lightweight Orbiter extruder allows you to achieve a complete carriage weight below 300 g (direct drive) and provide additional features such as ABL and easy cable and belts management. The printed carriage is also more rigid and compact.

+ compact and rigid
+ lightweight and well balanced
+ precise direct drive extrusion
+ better print quality
+ integrated BLtouch / 3Dtouch ABL sensor mount
+ easy cable and GT2 belts management
+ replacing the GT2 belts does not require disassembling the carriage
+ dedicated hotend and part cooling fan ducts
+ dedicated mounting bracket for filament runout sensor and reverse bowden
+ one hand nozzle change
+ increases the Z axis working area by about 8.5 mm

- slightly heavier than original bowden carriage
- increases the Z axis working area by about 8.5 mm
