Srry to bother you guys at 405th...

Umm... how much would the size for a pep EVA helmet be for a 10 near 11 year old? Cuz you gotta say somethin fast before I print the EVA helmet at height 30.0 centimeters

well it all depends on the size of your noggin...try for around 24 give or take...also just try measuring the height of your head in the mirror and add on like 3-5 cm .......remember if its not the right size, just remake it, iknow its alot of work but its worth it
and your not bothering us were here to help you with these things

30 is really big i would try 27 or under

i have a big head so i use like 26 or 27
