Brackets and feet for table using 2x4s

I designed these brackets to be used for making a table that uses 2 2x4s for its legs. The brackets are made out of Prusament PETG with 4 walls and 20% gyroid infill. For screws I used #10 x 3 inch screws it 100% does not need a screw in every screw hole that I put in the outer brackets but they are very strong if you do. for a tabletop I was able to find a coffee table at Goodwill for 10 dollars and I just took the short metal legs off of it. the models all have mirrored versions of themselves which I forgot to make for my own table and accidentally set up the legs wrong but it still works correctly. the table and legs are very strong I was able to throw a leg off of my porch and have it not break when it hit the ground. For the feet I printed them out of Overture TPU it was about 750 grams for all 4 and they work really well for absorbing vibrations and not sliding around.
