T-Post Trellis Support

We use t-posts and welded wire fencing to make trellises for our tomato and climbing plants. I've just used zip ties to hold them up, but these often fail. I went looking for a model to solve for this, and came across a t-post sign mount on Printables. I like the shape of it but it didn't quite fit the need. I remixed that model by cutting out a channel for the t-posts nubs to pass through, added a pin to retain the clip, removed the threaded hole and replaced it with a hook to hold the fence.
