Drain Rack V3 (Drain rack)

10/30补充描述（Supplementary description）：第一次打开模型的时候请从中间夹缝同时向内推进打开，单边用力可能会导致折弯。When opening the model for the first time, please push it inward from the middle gap, as unilateral force may cause bending. 经过各位使用者的反馈，对于二代的支架又进行了改进，这回我增大了支撑面积，可以晾干碗都没问题了，关键加量不加价，耗材仅需4.6克，而且采用了折叠建模，存放体积更小更方便。 After receiving feedback from users, I have made improvements to the second-generation bracket. This time, I have increased the support area and can air dry dishes without any problem. The key is that the quantity is not increased, and the consumables only need 4.6 grams. In addition, it adopts folding modeling, which makes storage smaller and more convenient.
