If you store the filament in a drybox, you might encounter a situation where the filament retracts back into the drybox, causing the filament on the spool to loosen. Installing this tool can prevent the filament from retracting back to the spool and, to some extent, prevent this issue.

As you can see, the filament retracts into the drybox, but not back onto the spool.

Print instructions

There are two directional options for the model: one where the filament exits the drybox from left to right, and the other from right to left. This only affects whether the filament path is fully visible after installation. If visibility is not a concern for you, you can ignore this difference.

Installation

1. Attach the "base" to the side of the drybox using glue or double-sided tape.
2. Thread the filament through the tool.
3. Mount the tool onto the “base”.
4. Pull the filament out of the drybox.
5. Pull the filament from outside the drybox, then push it back in to ensure the tool works properly.

Others

• If your retraction distance is particularly long, you may encounter problems, although I am not exactly sure what they might be. It is recommended that you consider shortening the retraction length.
• This tool may slightly increase resistance after installation, but it should not be a major issue. If the resistance is too noticeable, try adjusting the position of the tool to create a smoother angle for the filament path.
• If you have any problems or suggestions for improvement, please leave a comment.
• Please let me know how the tool works for you after installation. I look forward to your feedback!

中文介绍

如果你将耗材放入干燥箱保存，那么应该会遇到把多出来的耗材送回干燥箱的情景，回送耗材到干燥箱时，会导致料盘上的耗材变得松垮，安装这个小工具可以限制耗材回退到料盘，在一定程度上避免这个情况发生。

打印

模型有两个方向的区别，一个是耗材从左往右出耗材箱，一个是从右往左，仅仅是影响安装后能否完全看到耗材通过，不介意的话可以不管。

安装

1. 将**底座**通过胶水或双面胶粘贴在干燥箱侧边。
2. 将耗材穿过工具主体。
3. 将工具主体挂载到底座上。
4. 将耗材穿出干燥箱。
5. 从干燥箱外拉动耗材，再将耗材送回干燥箱，观察是否正常工作。

其他

• 理论上可以兼容所有料架，但我只有底座类型的料架，没有试过中轴类型或其他类型的料架。
• 如果你的回退距离特别特别长，也许可能大概会有问题，我不知道，建议你考虑缩短需要回退长度。
• 安装后，会略微增加阻力，但问题不大，如果发现阻力太明显，可以尝试调整工具位置，使耗材通过角度更加平滑。
• 目前没有进行太多复杂测试，如果你遇到什么问题或者有什么改进建议，欢迎讨论。
• 期待你安装后的效果，以及工作情况，请评论告诉我。
