3D打印新手教程｜用切片软件改模型尺寸，不缩放不剪切，布尔运算精确到毫米

网上下载的模型尺寸不合适？直接缩放，挂钩变形、镂空拉伸，根本没法用。本期用 Bambu Studio 布尔运算，手把手教你精确修改洞洞板收纳盒的长和宽，不缩放、不剪切，精确到毫米。 耗材：JAYO High Speed 哑光 PETG（铝箔袋包装，1.1kg，可拆卸料盘） 软件：Bambu Studio 2.8.2.61 空气质量实测：Panda Sense Pro 时间轴： 0:00 缩放为什么会变形 0:30 今天的方案：布尔运算 1:00 测量与计算 2:00 修改长度（切→拼→合） 5:00 修改宽度 7:00 打印成果与空气质量实测 新手看两遍就能上手。有问题弹幕评论区见。 下期预告：手把手打印安装 Panda Sense Pro 空气检测仪 合集地址：   / @xiaoyaosanhui   Downloaded a 3D model but the size is wrong? Scaling deforms the pegs and patterns. This tutorial shows you how to precisely modify model dimensions in Bambu Studio using Boolean operations - no cutting tools, accurate to the millimeter.
