Telescopic Back Scratcher

在设计了“鱼缸擦车窗擦2.0”（https://makerworld.com.cn/zh/models/1203077-yu-gang-ca-che-chuang-ca-2-0-fish-tank-wiper-car-w#profileId-1277650）之后，我意识到，如果将伸缩杆的工具头更换成痒痒挠的爪子，不就成为了一个可伸缩的痒痒挠了吗，于是就诞生了这个模型。模型打印容易，无需支撑。使用之后，感觉还不错。STP模型文件已经上传，欢迎下载并根据需要进行修改。 After designing the "fish tank wiper&car window wiper 2.0", I realized that if the tool head of the telescopic rod was replaced with the claw of an itch scratcher, it would become a retractable itch scratcher. That's how this model was born. The model is easy to print without requiring support structures. After using it, I found it works pretty well.The STP model file has been uploaded. You are welcome to download it and make modifications as needed.为我助力如果觉得有用，请为我助力，多谢多谢！If you find it useful, please give me a boost. Thank you very much!
