Infinitely Extensible Filament Rack

此无限延伸料盘架可以全部用打印机打印，建议使用PETG

建议采用3层壁厚，15%以上填充打印。本人上传模型为2层壁厚，15%填充打印，感觉强度可以，如果要堆叠较高，建议采用强度更高的材料。

该模型横杆X轴为210mm，可以放置3卷料盘，也可以放置未拆封料盘盒；

纵杆Y轴为190mm，为兼容更大料盘留有空隙，可轻松拿放；

Z轴为70mm，横杆粗18毫米，感觉强度完全够用。

连接处公差已设置好，建议先做三通与70mm连接杆适配自己机器。

PS：如果堆叠较高建议采用高强度材料、高填充度、高壁厚，外加胶水。

This infinitely extendable material tray rack can be fully printed with a 3D printer. PETG is recommended.

It is suggested to use a 3 - layer wall thickness and a filling ratio of over 15% for printing. The model I uploaded was printed with a 2 - layer wall thickness and a 15% filling ratio, and the strength seems sufficient. If you plan to stack it to a relatively high height, it is advisable to use a material with higher strength.

The cross - bar of this model has an X - axis length of 210mm. It can hold 3 rolls of material trays or unopened material tray boxes.

The longitudinal bar has a Y - axis length of 190mm. There is a gap to accommodate larger material trays, making it easy to pick up and place them.

The Z - axis length is 70mm, and the cross - bar has a thickness of 18mm. The strength is considered to be completely adequate.

The tolerances at the connection points have been set properly. It is recommended to first make the three - way connectors and the 70 - mm connecting rods to fit your own machine.

PS: If stacking to a high height, it is recommended to use high - strength materials, a high filling degree, a high wall thickness, and additionally use glue.
