I made this so that I could drape a net over our chicken coop area to keep predators out and not damage the net as it would hang over the T-posts.
It is a loose fit so that it may fit a variety of sized of T-posts, but the walls are tall enough so that it won't fall off of the post.
No supports required.
Sorry I don't have any pictures to post as of this initial post, but will try to get some soon.
The author marked this model as their own original creation.
