The prompt

请帮我设计一个“头重脚轻”的手持式仪器支架 3D 模型,用于导出为 STEP 文件。由于顶部负载很重,请务必保证底部的工程稳固性。 具体结构由下至上如下: 底部配重底盘:在坐标原点 (0,0,0) 的 Z 轴负方向,创建一个正方形底座。尺寸为长 100 mm、宽 100 mm、厚度 15 mm。底座的四个侧边做 10 mm 的圆角处理,防止割手。为了防滑和上螺丝,请在底座的四个角落各打一个直径为 4.5 mm 的贯穿沉头孔。 过渡基座:在底盘正上方,创建一个长方体过渡块,尺寸为 50 mm x 50 mm,高度为 20 mm,顶部边缘做 5 mm 的倒角处理,用于承受上方立柱的应力。 手持立柱:在过渡基座上方,向上延伸一个圆柱形把手。为了防滑和结构强度,圆柱直径加粗至 45 mm,长度(高度)为 100 mm。立柱底部与过渡块、过渡块与底盘必须完全融合(布尔并集)。 顶部安装板:在立柱的顶端,创建一个正方形平板,边长 144 mm,厚度 3 mm。平板中心在 Z 轴上,平面平行于 XY 平面。四个外侧角做 10 mm 的圆角处理。 顶部安装孔位:在顶部平板上打 6 个直径 4.5 mm 的贯穿孔,坐标分别为:(-55, 55), (55, 55), (-55, -55), (55, -55), (-48, 0), (48, 0)。 整体要求:从上到下所有部件必须融合为一个单一的实体(Single Solid),整体高度不要超过 140 mm。 请生成并直接输出 .step 文件供我下载。
