Mod Đầu In 2 Màu Lerdge iX Kiểu Raidy

The original file by Raidy is only one single layer thick near the hole of the direct extruder. Also, it has an unintended open space close to the cable outlet of the right radial fan. As a classical version user (non-linear rail) the left side of the printhead is slightly too wide by a few mm when homing, resulting in an undesired force on the head. 

Additional minor improvements are listed in the differences declaration.

Use supports for printing as necessary. A suggested 3mf is attached (beware that I used extruder 2 for printing, so adapt for your setup)
