3dlabprint style wing section

3dlabprint produce fantasic 3d printable RC aircraft (3dlabprint.com). Following printing their Spitfire, I thought I'd try to produce a wing section for a trainer style aircraft. This is what I came up with. definitely inferior to 3Dlabprint.

StantonFPV reciently did the same thing using a different technique. This has prompted me to publish what I came up with. See details in the youtube video https://youtu.be/ENtC-d1bXdM

It is designed to be printed with no infill, 1 outer layer, no top or bottom layers.
