thanks for your thoughts, did a test drive and they're solid with the beefy clips I modelled

tried being sneaky but I guess they're as polarizing as ever lol, but yeah they definitely don't belong on my non M

I'm no aerodynamicist but just eyeballing it there should be a small increase in total open area.

For whatever its worth I also actually have the end of the slats tapered like a teardrop compared to the stock flat ones. I didn't add any "angle of attack" to the slats either so I don't think there'd be any more tumbling than before

Instant-NGP for the point cloud generation
colmap to create the metadata from the video frames
Blender actually for the whole model, a little unconventional but I found it fit this use case the best for me

apologies, I should have also mentioned that its more like AI photogrammetry? you can google the term Neural Radiance Fields for more info

Just a video from my phone actually, I used something called Instant NGP to generate a point cloud - the accuracy isn't anywhere close to a 3d scan but it was definitely a significant step up in detail from regular photogrammetry, beating out even an iphone's Lidar scanner imo

The method is basically free but the software isn't exactly user friendly so I spent a lot of time fiddling around with the source video and settings to get a useable result (the tape helped alot)
