Sheet Screen Garter

I was looking for some way of stretching a sheet to make a screen for a yard drive-in. Nothing came up so I thought I'd try something.

This hasn't been tested in the yard yet but seems to hold a towel I tested it with. I'll likely tweak it once I give it a go.

Created in AutoCAD because that's what I'm familiar with.

Update: The v2 hub seems to work much better
