Filament Spool Hub

I needed a way to store paracord in an organized way to use in my kayak for my anchor line. I came up with this. It's a center hub that is 2.1" in diameter and designed to fit into a hatchbox 1kg filament spool. The knob is designed for a 1/4"-20 bolt and nuts. I trimmed down the spool to a more manageable size with a jigsaw, but you can leave yours full size for more storage is you prefer.
