This is a ring hook for remote controllers.

I bought a SwitchBot Hub Mini as a smart remote controller. I wanted to hang it on the wall without making a hole in it. So I decided to design a ring hook for curtain holdbacks.

Dimensions

• Major axis: 25 mm
• Minor axis: 10 mm
• Hook diameter: 3 mm (like M3 screw)

You can check the detail on my blog post (in Japanese). https://arundolon.hatenablog.com/entry/2022/02/11/232037
