Inspired by LTT's upcoming cable management accessory and Printable's user Edward's design.  This model is actually designed completely from scratch but is inspired enough by user Edward's design it would be disingenuous to not give credit and share as a remix instead.

This is a much larger clip being used by me to pin ethernet cables to the top of my server rack.  Could be used to pin any larger grouping of cables.  The magnets used are 20x10x5mm.  They definitely require being glued in place.
