I wrote a php file to convert all the airfoils from the http://www.ae.illinois.edu/m-selig/ads/coord_database.html ( about 1550 or so ) to scad and sdl files ( taking there cordanence, writing them to a openscad polygon, then using liner_extrude to make it 3d,I had to edit my base plate temp to 120c in order to make it not curl, I am not sure if that is just my replicator thoughtThe 7z file has all but the last 800 or so, I am going to bed now and it still is running so I wanted to upload what I have now, just incase anyone wanted to use them, I did a spot check of them and i would say 50% or so are ready to print another 25% need some minor tweeking on the bracket placement, and the other 25% are unusableAlso I uploaded the php file I used to create them, to run it you will need php installed ( and in the command path ) along with openscad installed, and change the path of openscad if it is not the same as what I haveI put the full database under a new thing http://www.thingiverse.com/thing:25170
