It is much easier to make a bicep than it is a helmet. Also, print a Bicep with the scaling you have decided for yourself to make sure that it fits properly. After you print, double check that all flaps have numbers on them. This may help other areas as well, where it could come through a bit tight. So you may want to add two or three inches to your actual height before doing the math. You don't really want the top of your head to be touching the top of the inside of the helmet if you expect it to fit right.

Note: Keep in mind: the size of the default scale that's in use before you edit is from the base of the ground to the top outside of MC's helmet.
