Bayonet Wire Spool

I created this spool to store enameled wire. The spool comes in two parts, main body and a cap, that are connected with a bayonet closure. Using two additional cone shaped brackets, the spool can be easily mounted to a screwdriver using M5 threaded rod with long nuts (see picture). To thread the wire in, I recommend to drill a hole corresponding to your wire diameter on the closure side. This way, the bayonet mount cannot release once the wire is wound up.
