Spool Cable Reel

A quick re-use for spent filament spool; turn it into a cable reel. I use it to store a long Ethernet cable.

Consists of a small handle to attach to the spool, and a removable insert to make holding the spool easy when spooling cable onto it.

Idea for the insert is to re-use it across spools of the same size. The handle is intended to stay on the spool, and is just a few grams of plastic - but it can be removed and refitted easily enough, just the clip structure on the handle components may wear over time.

The handle is in two parts; a flange/rod piece that fits from the inside of the spool (drill a 10mm hole in the spool to fit it), and the handle which slides onto the rod and clips into place. For strength, the rod has a hole for a 30mm screw - getting the diameter of the hole suited to a screw I did by trial and error; I think the screw I used is M4. Idea with the screw is just for strength to prevent the rod just snapping at a layer line.

Of course you could just buy a
