I really like your design. Will you add a hitch receiver or winch location? It will really increase the functionality of the bumper.
Here is a picture of my design. I first mocked it up with cardboard and then drew all of the individual places using 2D CAD with dimensions for laser cutting. It's been put on hold for now due to a shoulder surgery but I hope to get it cut out and tacked together by the end of the year.
The winch platform and some of the central brackets will be made out of 1/4" and the rest will be 3/16". The shackle mounts will be cut right into the main vertical uprights to save weight, complexity and avoid becoming points to snag on the rocks and dirt. They will be made from two 1/4" plates welded together.
I will also add tubing for grill/headlight hoops and supports underneath the side wings.
My priorities were to get the absolute maximum clearance possible and make it extremely strong, especially the side wings. I have a rear 4Xinnovations rear bumper and an ARB front bumper and its shocking how flexy the ARB is. It also gets hung up on everything. I calculated my bumper to weight in at 90 lbs. The tubing will add another 18-20 lbs.
