Hotend plates (tags)

In case you always like me forget the nozzle your printer has inserted.... Before layer 6 I added a pause and manually swapped the filament to white for the numbers.I superglued each 2 6mm magnets both on the inside of the hotend cover and the backside of the tags.The tags I dont use are sticking on the other hotends :-) It's one file with 5 tags:0.20.40.4H0.60.6H
