After seeing Peter Anson's 3D printed NACA vents on SonexAus, and how happy he is with them, I decided to do something similar so I started playing around with a design of my own. Spent a couple of evenings drawing which was a bit of a steep learning curve as I'm not used to 3D drawing. Anyway, today I took my first attempt to my friend who built his own 3D printer and he printed it for me. This was only a test print, off course this is far from finished as you can see but it's a good start and gives me a few ideas on how to take it further now.
