This is a simple 3D printing model that does not require support. It can be used to seal the exposed filament from the PTFE tube in a dry box. I find it very practical as I had a similar need before but couldn't find such a model anywhere online, so I had to make one myself. I have been using it for about two months now without any issues, and I am sharing it with everyone in the hope that you will like it too.

这是一个简单的3D打印模型，不需要支撑，简单打印，可以用来密封干燥箱特氟龙管裸露出来的耗材丝。
个人觉得非常实用，因为我之前有这样的需求但是找了下全网都没有这样的模型，于是我只能自己做了一个。
我一直在用，用了大概两个月了，都没有什么问题，现在分享给大家，希望你们能喜欢~~
