Here is an .stl . output from Scandy Pro/Meshmixer that I created of my head so that I can better scale my helmets for 3D Printing. I have also included the original obj exported files from Scandy Pro as well for anyone out there that wanted to tinker with those.
The STL file is 6.75 inches wide to match my actual head
Here is a link to my full video detailing Scandy Pro and editing the exports in Meshmixer
