Ender-3 v3Plus换料后，原耗材有很长一段在铁氟龙管外面，没法塞回干燥箱。各大平台的模型不适合我买的20 L米桶，于是参考原理进行了自适应设计，优化了尺寸并添加干燥盒，刚好能放下4盘，且耗材线盘不会被干燥箱的盖子卡住。

这个耗材架适用于20 L米桶，使用模块化设计，干燥剂盒子易取放。添加干燥剂时，干燥剂盒子侧面设计了一个开口，可选择安装湿度计，也可安装观察窗，以便观察干燥剂颜色。

这个模型没有特殊的结构，按自己的打印习惯切片就行，建议使用PETG更耐磨。打印数量标在各盘的名称上了，支架模块打印4份，干燥盒模块打印2份。耗材根据自己的情况调整，建议干燥剂的观察窗使用透明耗材打印，顶面设置熨烫。

安装方法：先将四个架子底座并排放置，用插销连接，然后安装滚轴，带齿轮的主动轴上建议缠绕羽毛球拍的缠带，以增加摩擦力。然后安装齿轮与穿孔轴（需要给干燥箱打四个过轴穿孔），平时穿孔轴用盖子轻轻盖住防潮，需要回卷时拿掉盖子换上转动拨片既可。回卷轴穿孔的另一侧的空间恰好放入2个干燥盒，最后在架子上放上耗材即可（过轴孔的另一面箱体上还需要打4个线材的穿孔，建议使用穿板气动接头）。

每个回卷模块还需要购买686轴承4个、106zz轴承3个、穿板气动接头一组。整个干燥箱需要4套，共计686轴承16个、106zz轴承12个、穿板气动接头4组，以及羽毛球拍缠带一卷。

使用后如有改进建议欢迎留言交流。

After changing filament on the Ender-3 v3 Plus, a long section of the old filament remains outside the PTFE tube and cannot be placed back into the dry box. Existing models on various platforms do not fit my 20L rice bucket, so I adapted the design based on the principle, optimized the dimensions, and added a desiccant box. It holds exactly four spools, and the spools are not caught by the lid of the dry box.

This spool holder is designed for a 20L rice bucket and uses a modular design for easy removal and placement of the desiccant box. When adding desiccant, there is an opening on the side of the desiccant box. You can choose to install either a hygrometer or an observation window to monitor the color of the desiccant.

This model has no special structural requirements. Simply slice it according to your usual printing habits. The required quantities are indicated on the names of each part: print four copies of the bracket module, and two copies of the desiccant box module. Choose the filament as needed. It is recommended to use transparent filament for the observation window of the desiccant box and enable ironing on the top surface.

Installation method: First, place the four bracket bases side by side and connect them with pins. Then install the rollers. It is recommended to wrap badminton grip tape around the geared drive shaft to increase friction. Next, install the gears and the through-shaft (you will need to drill four holes through the dry box for the through-shaft). Normally, keep the through-shaft covered with a cap to prevent moisture. When you need to rewind the filament, remove the cap and replace it with a turning paddle. On the other side of the through-shaft hole, there is exactly enough space to fit two desiccant boxes. Finally, place the filament spools onto the holder (four additional filament pass-through holes will also need to be drilled on the opposite side of the box; it is recommended to use pneumatic push-to-connect fittings).

Each rewind module requires four 686 bearings, three 106zz bearings, and one set of pneumatic push-to-connect fittings. Four sets are required for the entire dry box — a total of sixteen 686 bearings, twelve 106zz bearings, and four sets of pneumatic fittings.

If you have any suggestions for improvement after use, please feel free to leave a message to discuss.
