Aluminum profile hook

This is a specialized hook for 40X40 aluminum profiles, which needs to be placed in the aluminum profile slot in advance and disassembled later.Because it requires a certain level of strength, it is recommended to use high-strength materials such as PETG for printing. I have set a layer height of 0.16, 50% filling, and four layers of walls.Its empty size is 1cm, please do not enlarge it because it is small, otherwise you will not be able to use it. 这是一个40X40铝型材的专用挂钩，它需要提前放置到铝型材卡槽中，后期需要拆卸铝型材。因为它需要一定的强度，建议PETG等高强度材料打印，我设置了0.16的层高，50%的填充，以及四层墙。它的空的为1CM，请不要因小而放大它，否则您将无法使用。
