My solution for crossbar wind noise (requires 3D printer)

[IGR]

I made this plastic inserts a while ago, figured I might share it as well.

Link to files: https://www.printables.com/model/791507-rivian-crossbar-inserts-set-of-180mm-270mm-540mm-l

Printed in 3 peaces from ASA, PETG should work too but I think ASA is better for UV resistance.
I think you could also print this in color to match paint of the truck.

The set for a pair of crossbars would cost about $1.50 in filament, and 4.5 hours on modern printers.

In slicer it can be cut or shrink/extended to fit your specific application, in picture below I scaled it to fit with my crossbar mounted KC lights.

This is picture from test pieces I made (PLA), it actually removed the whistling noise. Tested on highway.

I still yet to upload it to a websites fro 3D printed parts, can anyone recommend a good site? I think I will try printables . com...

Printables is your best bet!

If it's in direct sun, I'd go ASA for the UV resistance. PETG will end up fading.

+1 for printables. That's practically the only place I upload to these days.

I've not had any wind noise issues, but I'll keep this in my back pocket should it ever become a thing... thanks!

A while back, someone posted on one of the forums that this product worked for reducing wind noise on Rivian Cross Bars

Funniest part of this joke is $300 for a printer. Sure you can go get your ender for that, and the first thing you'll do is spend $300 more and hours upon hours on enhancements actually making it "work"

Works really well.

I think nowadays you can get a decent printer for that money that works out of box. I had no issues with QIDI, and even at work we use their commercial variant.

@RWerksman & @R1Thor I just uploaded files to printables, thanks for advice

Thanks for this! Once I figure out why the heck none of my prints are sticking to the bed, I’ll print these. I’ve printed a few things which came out great and now nothing wants to stick. I’ll have to do some more troubleshooting.

I feel you, this is the hardest part when you use more advanced filaments like ASA, Nylon, PC, etc... it took me a few tries to get it right.
In case of ASA it likes to warp, so what worked for me is dialing Z-offset down to +/-0.01mm, luckily this particular print is low profile so it doesn't get a chance to warp.
Good luck!

I like printables.com. would love to try this if you post it.
I had whislting from my cross bars and put electrical tape in the leading edge of the vetricle struts over the seam. Saw it on a reddit post and it actually works
