Lelit Bianca Coffee level tool

Inspired by the Breville / Sage Razor tool. This is used to ensure that the volume of coffee once tamped isn't too much (coffee hitting the shower screen) or too little (Wet puck).To use it, try to scrape the top of your puck like in this image, if it's far from touching, add coffee, if it scrapes remove some coffee. This tool has been tested with the Lelit Bianca V3, I can make one for other machines if you provide me the ideal height of coffee from the portafilter Edge.
