型号zk-fx35电子负载仪，默认底部只有4个柱子支撑，电器件暴露在外，桌面上金属物品很容易导致其短路烧坏，我为其设计了一个底壳，使用m3的自攻螺丝固定4个螺丝孔（M3X8（长点短点都没问题）），对于发热的位置预留通风道，电源孔也有，设计潦草，还望海涵。

The model zk-fx35 electronic load tester has only 4 pillars at the bottom by default, and the electrical components are exposed to the outside. Metal items on the desktop can easily cause short circuits and burn out. I designed a bottom shell for it, using m3 self tapping screws to fix 4 screw holes (M3X8 (long and short points are not a problem), and reserved ventilation ducts and power holes for heating positions. The design is sloppy, and I hope for your understanding.
