I designed a card reader holder for the UGreen SD card reader. I use SD cards for my 3d printing and I wanted something that was easy to mount to my desk. I mounted this right at the lip of my desk so i can easily access the SD card reader for faster prints. This mount is great for this SD card reader. I mounted the unit on my desk with #6 X 3/4 metal pan head screws that can be purchased at any big box store. Attached below is the link for the UGreen SD card reader.
