I needed a dozen or so of these, and there was no reason to purchase the metal ones from Secret Lab when I could knock together a quick model print and attach magnets. I printed these in Ultra Silk Red from Eryone to match the rest of my Magnus Pro desk layout. I have included the Secret Lab logo as well for consistency.

Really quick and easy print.
I glued 20x5x2mm magnets in the slots to hold it down to the desk. These are the magnets I used for this (amazon). These are more than strong enough to hold them down and cables neat and tidy (unlike the rest of my desk LOL)
