Gidday Troy, I thickened the shell, creased and sharpened the lines and smoothed it where possible. I even seperated some parts that were floating for easier printing. Just needs to be printed as is or split further to accomidate a smaller print bed. I'll try and slpit it where I can.
I've also enlarged it so the whole at the bottom is 17cms wide. So the average adult mail can put it over there head. I look forward to your model if and when you get round to printing it ; ) Cheers Jace
