Please note this is an untested print.
Inner whole from left to right is 16cm wide incase you want to increase or decrease the size to suit your head. I have slice it as best I could to print, but there was a couple of objects that will need a little support. I've included other files incase you want to improve on it further. Please post some pics if you do give this a go to print, Cheers Jace
