Inspired by SecretLabs cable sheath. I didn't want to put any double-sided tape under my desk or drill any screws in and I already had a standing desk which has a metal frame. Couldn't find any existing designs so made my own and thought I would share.

I think I have attached the STL file, if anyone wants to remix; though I think I messed up my timeline and deleted things that are dependet :S 

I used 10x 6mmx2mm neodymium magnets with some super glue which is more than enough.
