Here is one idea that considers environmental issues.
I made an eco-friendly garbage bag holder using a plastic bag.
You can brush dust off by hand because it is under the side of desk.
The thickness of the table that can be attached is Max 36mm.
If you attach a rubber cushion of 8mm diameter and 2mm thickness to the blue arrow in the last photo, you can attach it to the desk more firmly.
Designed to match 3M cushion CS-04.
See my blog for more information. (it's Japanese)
