I haven't found a way to put it on marketplace so I'll leave it here.
I've done group order at modular addict but friend of mine changes his mind leaving me with a lot of cables I have no use for.
So I'm selling stackable and thin cables form modular addict with -15% off and shipping from Poland. If anyone is interested feel free to contact me and make sure you do before I sell them all (hopefully).
