I'm hoping that releasing this design does not upset anyone at Lumenier. I am not making money off of these and I doubt that they plan to release an aero-guard with the logo embedded in the side of it. If anyone from Lumenier sees this and would like me to take these down, please let me know and I will do so promptly. This is a remix of this design: http://www.thingiverse.com/thing:617553, which was a remix of this design: http://www.thingiverse.com/thing:583027 There are 2 versions. One was thinned out in the middle to save weight. A set of these weighs around 16 grams. The other version is the original thickness and a set of these weighs around 21 grams. I printed mine face down in PLA on blue painters tape. Try and use very wide tape or get the gaps between the tape extremely small and you will get a nice matte finish that looks good in contrast to the glossy carbon fiber.. One last note: when I first used 3D-printed aero guards without any holes in them, I had uncontrollable yaw issues. It was super twitchy and would whip around wildly with even mild yaw input. This same issue has occurred for some people when using the thin, flexible aero guard that Lumenier sells. (You will notice that they now have a disclaimer on their site stating that they are aware of the issue). Once I put the logos (holes) in these, the yaw issues that I was experiencing went away completely.
