在Makeworld上一直没找到角度合适、可以放置机械键盘的笔记本支架，于是自己建模，适配R9000p（2024）、可以放置75配列机械键盘（Hi75c）的笔记本支架，打印时可以不用支撑，一盘打印，中间部分应用榫卯结构，放置笔记本后很牢靠，基本不晃动，并且不用胶水，方便拆卸。文件中同时上传stl格式，方便大家自行修改。本人是初学建模，请大家多提宝贵意见。

After searching Makeworld in vain for a laptop stand that tilts just right and still leaves room for a 75 % mechanical keyboard, I designed my own. It’s dimensioned for the 2024 Legion R9000P and clears a 75 % board (tested with the Hi75c). The whole thing prints support-free; the mid-section uses a traditional mortise-and-tenon joint that locks solid once the laptop is in place—no wobble, no glue, and easy to take apart. STLs are included so you can remix freely. I’m new to 3-D modeling, so any feedback is welcome!
