More smoothy

首先感谢原作者的设计，设计的非常精妙，但我在长时间使用后还是出现了不顺畅的问题。于是我尝试发现问题的所在。Firstly, I would like to express my gratitude to the original author for their ingenious design. However, after prolonged use, I still encountered some issues with smoothness.So I tried to identify the problem.我发现耗材会特别容易卡在画红圈的这个位置，因此我想设计一个可以使耗材顺畅通过这一区域的零件。I found that consumables are particularly prone to getting stuck in the red circled area, so I want to design a part that can allow consumables to pass through this area smoothly.这是一个非常简单可以快速打印出来的零件，内部结构图是锥形的方便耗材更顺畅的通过。This is a very simple part that can be quickly printed, and the internal structure diagram is conical, making it easier for consumables to pass through more smoothly. 这是原作者发布的作品链接。This is the link to the work published by the original author.https://makerworld.com/zh/models/18174#profileId-17021
