Over time as I've upgraded from one 3D printer to another I've ended up with quite a surplus of nozzles. I have three .6mm Nextruder nozzles and three .4mm Nextruder nozzles all in great shape and several of which are new. These will never be used and are squirrled away in a drawer and not even next to the printer (which has 5 nozzles of its own).
The surplus is mainly due to switching to a high flow printer and also the use of materials requiring hardened nozzles.
