I designed a new X axis movment part with extruder holder together. the ID 16mm hold uses for installing proximity detector. what’s your opinion?tell me thank you.

This will be hard to print, it will require a lot of support.
What is really the advantage of combining the carriage and the extruder?
You save some weight from mounting screws?
@Oystein_Krog I wanna save some weight to make the X axis lighter. the another reason is the old design uses nylon cable ties to fix the linear bearings.
