bed glass clip for CR2020

我一直在找能固定好热床玻璃，又不用占用打印面积的玻璃夹子，但遗憾的是没有发现很合适的，所以我做了这个。目前使用效果还可以。但需要更多人来测试和修改，STP文件已放出，希望大家能帮助一起完善，谢谢！

I have been looking for a glass clip that can fix the hot bed glass without taking up the printed area, but unfortunately I didn't find it very suitable, so I did this. The current effect is ok. But more people need to test and modify, STP files have been released, I hope everyone can help improve together, thank you!
