It’s tough for there to be any one best cable management solution, because everyone’s needs are so different. In this case industrial designer Eric Strebel needed something to hold the necessary cables in his sound recording booth, so he designed and built his own.
During the video he touches on the all-important topic of time management (your time, versus a machine’s time), evaluates Polysmooth filament and shows you how it can be touched up with rubbing alcohol.
Strebel’s posted the build files for free on Thingiverse.
