Edit 5/7/2017 : "TEC" did amazing finishing job on this Genji helmet, He even fixes the issue I have hear that some people were having with the back o...f helmet with magnets. Check out his video here: https://youtu.be/BcwIi8op7Yg
Edit 5/1/2017 : Current helmet should now fit an adult head at 100%. Please check dimension picture to make sure it will fit.
Edit 4/28/2017 : I added a dimensions of the helmet to help with sizing. Units are in millimeters.
I was asked to make an Overwatch Genji Helmet so I decided to share it here too.
This helmet was designed for a child so if you want to print it for an adult I would print at 110%.
I added pictures of the helmet assembly.
