Summary

I got a new Dell computer, with a 130W power supply (DA130PM170). Dell didn't even supply a velcro strip to keep the wires together when you carry the computer around.

Just to get by, I used a rubber band - but how long was that going to last... So I did the same thing with the 3D printer. This ring holds the cables securely, comes on and off easily, and won't break or get lost as easy as a rubber band. I think I even like it better than the velcro strip.
