I’ve just uploaded a new model, the Aviation Boatswain’s Mate wings. This one has an extra stl file in style a for 3d printing. The cnc style at has very little material at the contact point between the wings and anchors. I doubt the wings would stay attached done with a 3d printer that way, so the extra stl has more material surrounding everything to give it some strength. This is not reflected in any of the pictures.
