Jeep Tie Down

I designed this for my 2005 Jeep Liberty. I was replacing the carpet in the rear and the tie down were riveted in. The rivets spun when I tried to dill them so I had to cut through the side which ruined the current tie down which were $10 each so I printed replacements. Which are stronger then the originals because of 100% infill which may not be nessacary but I wanted them to be as strong as possible. I have installed them and they work great.
Any question I would be happy to answer.
