I want to 3d print out some pilot busts. There are a lot of really cool models if you search for "bust" on thingiverse. The problem is trying to figure out the correct dimensions to match my 1/7 jet. I even went shopping around for premade pilot busts and they all reference scales but not any dimensional sizes. I guess i could measure my head and calculate it down, but just seems like i am searching for the wrong terms as im not finding anything already online for these numbers.
