I had to model a section of U-Post signpost for a TV commercial shoot. We needed to attach a sign temporarily and the posts did not go high enough.
Somewhere, someplace, there is another prop person who will find this and shout "YES!" to the heavens! Other than that, I suppose you could use it to attach all your stolen sign collection to?
Made sure you have good bed adhesion. Just place it vertically and let it go. You might have to chop it to the size of your printers Z.
