这是一个简单且方便打印的挂钩，适合挂在门上。我制作了四种不同的大小款式，这可以适配厚度在40-52mm，与门框缝隙在2mm以上的门，它的挂钩较长，可以挂书包等物品。

我使用petg打印了这个挂钩，它可以承受5kg以上的重量，不过这会使它有些弯曲，所以我建议你不要挂3kg以上的重物。

虽然我在设计时采用了圆弧，但我减小了圆弧的弧度，使它美观实用并且可以轻松打印

This is a simple and easy to print hook that is suitable for hanging on doors. I have made four different sizes of styles, which can fit doors with a thickness of 40-52mm and a gap of more than 2mm with the door frame, and it has a longer hook to hang items such as school bags.

I printed this hook with PETG and it can hold more than 5kg, but it will bend it a bit, so I recommend that you don't hang more than 3kg of weight.

Although I used a circular arc in the design, I reduced the arc of the arc to make it beautiful and functional and easy to print
