Somehow the strips covering the channels in the underside of our Thule Wingbars went missing. It turns out that above about 65mph, the car makes a very loud whistling noise without them. It also turns out that they're reasonably expensive to get replacement parts for.
This a model for the replacement strips I made in 95A TPU. They are not an exact match of the Thule part (which is made of something like ABS), but fit perfectly into the slots on my rails and have some extra thickness in the side walls. I printed these with no supports and had no issues.
Depending on the fitment for your car, you might find the slots are longer or shorter, and you'll need to scale them lengthwise to fit (make sure to TURN OFF ‘uniform scale’ so only the length is changed!)
These have been working fine for me for a few hundred miles of winter weather so far!
