Very clean cable routing

I have 4 computers (Windows, Ubuntu, association, company) 2m connected to a trolley ca from desks Switchbox with screen / mouse / keyboard and to the router. Thus 9 cables are "hidden" in the bundler: 3 thick (for printers, monitors, power) 3 medium (network cable) and 3 thin (Mouse, Keyboard, Audio). Result: It looks very clean and there is still space in the tube! Threading Another cable (with me the power cord) was no problem.
The only drawback is the insertion aid. She is very weak. So I had to insert the cable start again, because the spring that holds the two wing parts fell off. When 2.Versuch we went but then very good. Behind the ends of the tube I have the cable secured with one cable tie to prevent later additions out slips.
