A great way to keep your spare nozzles. You can print it in different colours and in two versions, as you prefer. I use the first column for used nozzles and the second column for the still new ones.

In the first version, the nozzles are screwed into their placements; in the second version, the nozzles are simply placed in the holes from the hexagonal side.

Hope you enjoy both of them.

If you want, change filament colour (if your printer has pause mode) when it is printing numbers and another time when it finished printing numbers and started with the holes.

Use ironing option to have a nice surface.
