Patch to Surf Conversion

We have the following code defining a pair of wings using the patch function. We are trying to convert the .m file to an .stl file however the surf2stl will not work as the wings are not defined using the surf function. Is there any way to resolve this? Thanks.

figure(1)

v = [0 -15 60; 0 -15 57; 75 -10 60; 75 -10 57; 78 5 60; 78 5 57; 0 0 60 ; 0 0 57; -78 5 60; -78 5 57; -75 -10 60; -75 -10 57];

f = [1 2 4 3; 3 4 6 5; 5 6 8 7; 7 8 10 9; 9 10 12 11; 11 12 2 1;7 1 3 5; 9 11 1 7; 2 4 6 8; 2 8 10 12];

wing = patch('Faces',f,'Vertices',v,'FaceAlpha',1,'FaceColor','green');
axis equal

After R2018b, MATLAB has STL tools in the base toolbox:

stlwrite()

Prior to R2018b, I'd agree with the recommendation of FEX #20922
