A simple method to remember the size of the printing nozzles when using various printers and different types of filament.

I use it mainly on my Qidi X Max printers, where the nozzle size is really difficult to find if you have forgotten it.

Simply attach the support plate with a bit of double-sided tape where you want and hang the correct size measure of the nozzle in use.

About 20 grams of plastic and less than 1 hour of printing time.
I printed it in two colors of PETG, which is the filament I use most often.

I also suggest a few mm of outer brim or a good washing of the build plate!
