I was inspired by a picture on Reddit, which you can see of a car covered in pool noodles. Here in South Texas, we get are fair share of large sized hail, and this seemed like a cheap way to protect your car. The original picture appeared to use zip ties.
I thought that a polypanel would be a great way to add 3D printing into the mix. I took the connector only file and edited it in Fusion 360 to have the circular center as well as a mirrored connector on the other side. This was sized around a pool noodle I had in the house, but could easily be changed.
The idea here would be, print enought connectors (2 per noodle) to cover the length of your car. Once you get to the end,I would suggest running some rope through the first/last noodles to tie down the whole thing securely.
