Minimal US Shoe Size Tool

I took the shoe size measurements on nike's page for mens shoes, and translated that into a very minimal one piece print to take your shoe measurement at home. 

Under 4 grams of filament required, prints on a Prusa MK3/MK4 in one piece. 

Can do some simple layer swaps to make it easier to read, and it will look nicer when printed with a 0.4 nozzle than my pictures (I used a 0.6 nozzle – but it's still perfectly usable!) 

Just put your heel back up against the raised back area, stand on both feet like you naturally do, and look to see where the longest part of your foot extends to. The notches are at each half size – each full size is labeled (the notch above the number is the measurement) 

In the included picture, I am a size 13 for reference.
