将所有图标的旋转调整正确

```python

import bpy

import os

import re

input_dir = r"E:\3DPrint\FF14ZhiYeTuBiao\stage1"

output_dir = r"E:\3DPrint\FF14ZhiYeTuBiao\stage2"

# 自动创建输出文件夹

os.makedirs(output_dir, exist_ok=True)

def strip_leading_digit(filename):

    # 去掉前导的1/2/3，只保留一次.stl后缀

    name = re.sub(r"^[123]", "", filename, count=1)

    return name

bpy.ops.object.select_all(action='SELECT')

bpy.ops.object.delete()

stl_files = [f for f in os.listdir(input_dir) if f.lower().endswith('.stl') and not f.lower() == "hole.stl"]

for model_name in stl_files:

    # 判断旋转角度

    prefix_digit = model_name[0]

    rotation_z = 0

    if prefix_digit == "1":

        rotation_z = 90

    elif prefix_digit == "2":

        rotation_z = 180

    elif prefix_digit == "3":

        rotation_z = 270

    bpy.ops.object.select_all(action='SELECT')

    bpy.ops.object.delete()

    model_path = os.path.join(input_dir, model_name)

    bpy.ops.wm.stl_import(filepath=model_path)

    model_obj = bpy.context.selected_objects[0]

    model_obj.name = "TargetObj"

    # 旋转

    if rotation_z != 0:

        bpy.context.view_layer.objects.active = model_obj

        model_obj.select_set(True)

        bpy.ops.transform.rotate(value=-rotation_z * 3.14159265 / 180, orient_axis='Z')

    # 导出文件名去掉前导数字

    export_name = strip_leading_digit(model_name)

    if not export_name.lower().endswith('.stl'):

        export_name += '.stl'

    output_path = os.path.join(output_dir, export_name)

    bpy.ops.object.select_all(action='DESELECT')

    model_obj.select_set(True)

    bpy.context.view_layer.objects.active = model_obj

    bpy.ops.wm.stl_export(filepath=output_path)

print("批量旋转并导出完成！")

```

Stage 2 -> Stage 3:

blender

将所有图标的左上角打孔，这一步处理前一定要先修复模型！

```python

import bpy

import os

import bpy

import os

input_dir = r"E:\\3DPrint\\FF14ZhiYeTuBiao\\stage2"

output_dir = r"E:\\3DPrint\\FF14ZhiYeTuBiao\\stage3"

hole_path = r"E:\\3DPrint\\FF14ZhiYeTuBiao\\hole.stl"

# 偏移量（如需打孔稍微往右下移，可调整，单位同模型）

offset_x = 2

offset_y = -2

offset_z = 0.0

def get_bbox_min(obj):

    return [min([v[i] for v in obj.bound_box]) for i in range(3)]

def get_bbox_max(obj):

    return [max([v[i] for v in obj.bound_box]) for i in range(3)]

# 自动创建输出目录

os.makedirs(output_dir, exist_ok=True)

# 清空场景

bpy.ops.object.select_all(action='SELECT')

bpy.ops.object.delete()

# 加载hole.stl

bpy.ops.wm.stl_import(filepath=hole_path)

hole_obj = bpy.context.selected_objects[0]

hole_mesh = hole_obj.data.copy()

hole_min = get_bbox_min(hole_obj)

hole_max = get_bbox_max(hole_obj)

bpy.data.objects.remove(hole_obj, do_unlink=True)

# 遍历stage2下所有stl

for model_name in os.listdir(input_dir):

    if not model_name.lower().endswith('.stl'):

        continue

    bpy.ops.object.select_all(action='SELECT')

    bpy.ops.object.delete()

    model_path = os.path.join(input_dir, model_name)

    model_obj = bpy.context.selected_objects[0]

    model_obj.name = "TargetObj"

    model_min = get_bbox_min(model_obj)

    model_max = get_bbox_max(model_obj)

    # 计算hole应放置位置（左上角：x最小，y最大，z最小），要对齐hole的最小x、最大y、最小z

    hole_location = [

        model_min[0] - hole_min[0] + offset_x,

        model_max[1] - hole_max[1] + offset_y,

        model_min[2] - hole_min[2] + offset_z

    ]

    hole_copy = bpy.data.objects.new("HoleCopy", hole_mesh.copy())

    bpy.context.collection.objects.link(hole_copy)

    hole_copy.location = hole_location

    # 布尔差集

    bpy.context.view_layer.objects.active = model_obj

    bool_mod = model_obj.modifiers.new(name="Boolean", type='BOOLEAN')

    bool_mod.operation = 'DIFFERENCE'

    bool_mod.object = hole_copy

    bpy.ops.object.modifier_apply(modifier=bool_mod.name)

    bpy.data.objects.remove(hole_copy, do_unlink=True)

    # 导出

    bpy.ops.object.select_all(action='DESELECT')

    model_obj.select_set(True)

    bpy.context.view_layer.objects.active = model_obj

    output_path = os.path.join(output_dir, model_name)

    bpy.ops.wm.stl_export(filepath=output_path)

print("批量左上角打孔并输出stage3完成！")
