Try that one. It states that is a "Strong and Flexible plastic". I figure that I would try it before I go and try to make them myself. They won't let you make it publicly available until there is at least one confirmed printing.
Thanks
Well I got them back from my 3D Printing Adventure. They look sturdy and they should work. I designed them with a Pilot hole to make it easier to drill and tap to the correct size. But they turned out alright. Here are some pictures.
The ones for my Satellite are expensive & I was looking at them. And the base is the same style as the license plate holders. So I bought a bunch of them and they worked. If you have a square hole or aren't concerened to file the hole you can use these
