Helmet Fit Guide

I needed something to help me decide my correct motorcycle helmet size based on the manufacturer's size guide.

Pro tip: You can remove it while still hot from printing, immediately put it on your head and "mold" your head shape. Some websites offer helmets in categories of your head shape (round, intermediate oval, long oval).

Printing this model in different sizes proved to be way easier than using tape measure, as you will be able to tell how snug the helmet will be.
For my preferred size I can barely put a finger between my head and the band when worn.
