Chainable Ethernet Cable Holder with cap (Wall-Mountable)

I found myself in need of a way to organize ethernet cables within the rough width of a wall-mounted rack. I wanted the holder to be able to be chained for as many as needed to make things aesthetically pleasing so I came up with this. 3 of these will handle a single 48 port switch and the included cap can fill the gap at the end to make things secure, or print a second cap to have both ends "nice and thick".
