This is taking me a hell of a long time to complete.
There are still transitions on the mask im not 100% happy with, and now everytime I change somthing this alters the connections to the ajoining surfaces, so im a little worried about mucking up my work. Im also quite stumped atm at how the (nearly invisible) mask front connects with the gas mask piece. aaaaagh.
And this is before I do all the subtle filleting and champhering of edges and make sure they all line up perfectly (because the slightest % of a mm gap will make holes in the 3d print)
I am also out of milk for my coffee, Time for a stroll in the sun (thank you weather).
