I needed to tidy up all the cables behind my desk and, after using some adhesive solutions I decided to go for a permanent solution because adhesives can either be messy to remove or fall off within a few weeks. I made velcro strap holder that can be fixed in place with a screw, the velcro strips that it can hold are 1cm wide but you can easily edit stretching it in Cura, it's really easy to mount.
