This is a hook that can hang anything on any board or stick, no matter how heavy the object is, this hook will never fall off or break (unlike when using glue or double-sided tape).

The best part is that, I've provided a SCAD script so you can easily customize the size!

这是一个可以把任何东西挂在任何板子上、棍子上的挂钩，无论你要挂的东西有多重，这个挂钩永远不会脱落或断裂（不像用胶水或双面胶）。

最妙的是，我提供了SCAD脚本 ，你可以轻松定制尺寸！

There are several parameters you can tweak. I draw a simple illustration as follows. Make sure to measure your item's dimensions and adjust the parameters accordingly.

Basically:

• w1= board thickness
• w2= item thickness
• h = item height
• l, d, thickness: they are responsible for the strength of the hook. Usually, you need not change them, unless your item is really too heavy.
