鱼缸喂食环

设计初衷：因为自己养了一个小鱼缸，喂食时，饲料经常被过滤器吸走，为了给鱼儿喂食，所以参考网络上的类似设计，自己做了一个喂食器。 鱼缸圆形喂食环，内径94mm，外径105mm，高度11mm，连接杆长度54mm左右。 喂食环主体打印做好是0填充，保证内部有充足的空间（空气）可以提供浮力，否则喂食环无法浮在水面。 连接杆两端的卡扣建模时留了0.2的间隙，但可能因为打印时的冷收缩，间隙可能会变大，我认为这刚好合适。 两个模型有搭桥的位置尽量开启支撑，打印完成后用指甲一掰就掉了，因为模型与打印板接触面积过小，尽量开启Brim。 The circular feeding ring of the fish tank has an inner diameter of 94mm, an outer diameter of 105mm, a height of 11mm, and a connecting rod length of about 54mm. The main body of the feeding ring is printed with zero filling to ensure sufficient space (air) inside to provide buoyancy, otherwise the feeding ring cannot float on the water surface. When modeling the buckles at both ends of the connecting rod, a gap of 0.2 was left, but the gap may increase due to cold shrinkage during printing. I think this is just right. Try to open the support at the bridging position between the two models as much as possible. After printing, it will fall off with a fingernail because the contact area between the model and the printing board is too small. Try to open Brim as much as possible.
