I'm a network engineer and needed something to keep all my Ethernet cables in my bag from getting tangled up. It is sized to be a large as my printer can handle (6" diameter) and also keep the bend radius within spec for CAT5e. The openings have been sized for standard Ethernet plugs. I have been using a 3 meter cable and it has plenty of room to spare. I'm guessing it can hold a 5 meter cable, but I haven't found one yet to load into it.

I patterned this after similar spools I saw for US
