This design is used to protect the USB cable from breaking at the connection. I made the design both in OpenSCAD and FreeCAD so you can edit it based on the size of your cable.

You will need these dimensions like in the photos to make your own version.

With OpenSCAD, you can edit the file directly from thingiverse If you use FreeCAD, you can modify the parameters in the Spreadsheet. More details can be found here: https://gubutek.wordpress.com/2021/06/18/usb-cable-saver/

I added some referenced dimensions of my cables in case you need.
