Current nozzle indicator

Update:I redesigned a shorter, V2 version. The print profile also now is print by object, allowing for a single change of filament and a less than 30mn print time! Original description: If you keep forgetting which nozzle is in your printer, use this simple indicator to always know at first sight what nozzle is in use! Just don't forget to change it after you've changed the nozzle. Designed to be glued to a surface (might be the printer itself), the sliders don't hold on their own. You will need some double sided tape. Can be printed in a single color, but might be harder to read if so. Print several at a time to minimize poop waste.
