Mounting A Usb Cable Neatly

I’m curious how any of you have mounted a USB cable “permanently” to the handlebars. I use a RAM claw mount that I move to other bikes and like to ride the ST sometimes without my phone mounted. The cable run from under the seat to the front is done and I’ve been using it but when I remove the phone mount from the bars the cable is around and I would prefer something nicer than zip ties or Velcro strips. Any ideas?
