This is an X carriage for a CoreXY printer which support dual color printing. I installed a E3D Cyclops as hotend and two E3D Titan extruders. Since I designed my own parts from scratch for my printer, the measurements might be different then most printers. The two sliders for the carriage are seperated 53 milimeters and have a diameter of 10 mm.
The carriage is designed to hold a 3DTouch sensor and in combination with an adapter ( part 04.stl ) , which you can find here also, you can use an inductive sensor too.
Parts 05 and 06 are there to hold all the cables, coming from the different parts.
On the side of the carriage, there is also a support for the X limit switch.
