Modifications and optimizations have been made to the official P2/X2 models, including:

1. Adding a slot to the glass cover holder to avoid screws on the cover handle, resolving the issue of screws hitting the cover.

2. Adjusting the printing direction and position of some printed parts to adapt to X2D's dual-support design.

3. Setting variable layer height for some parts with many curved surfaces and manually adjusting some areas that might fail to print.

4. Modifying some unreasonable screw hole positions to prevent breakage.
