Parametrizable USB Cable Protector by kdv0403 on Thingiverse: https://www.thingiverse.com/thing:4138005

Summary:
I haven't found a protector for the second ending of the cable (USB Type A), so I added it's model. Due to the various sizes of different manufacturer's plugs I generated ones for Samsung Galaxy S7 and Xiaomi Redmi 6A. UPD: I've tired to remake the model in sketchup for each cable I've printed a protector for. So I've made a script for OpenScad where you can set your own cable's sizes and generate stl in a few minutes.
