About this model

水分子H₂O球棍演示教具，H‑O‑H键角104.5°。氧原子（O）直径84mm，氢原子（H）直径42mm，为避免球体互相干涉，同时便于直观展示共价化学键，化学键连接杆做了加长处理；并非真实键长等比例缩放，属于示意教学模型、艺术摆件。附带可拆卸展示底座支架，可以直接摆放于桌面、讲台进行课堂演示。分件打印，无需AMS！需要少量胶水粘接字母与化学键连接杆。注意事项：1、机器公差与耗材收缩率等问题，有概率影响装配。（预留公差0.2MM）2、缩放模型为未知选项，请谨慎操作！3、打印前务必清洁打印面板，不要用手触摸打印工作面，降低炒面、喷头裹头概率。4、发布的3MF文件已完成装配实测验证。‑ 🟢新手：直接使用原始3MF，仅修改耗材参数即可打印；不要更改摆放方向、不要大幅修改模型，避免装配失效等未知问题。‑ 🟡老手：可自由发挥，并欢迎反馈问题与优化建议。为我助力十个八个助力不嫌多~一个两个赞不嫌少！
