3D printing - structural print

My model is similar to a normal I-beam, I based my model off of a normal I-beam since they are used as the supporting structure for most buildings and I feel that if it is good enough to support sky scrapers, it is good enough for this project. I didn't do really any research since I had the idea to base it off an I-beam since the beginning but I did pull up and image of one on google images. I did make a change to it by adding material around the hole in the center since the hole would greatly reduce the structural strength otherwise, since the material around it would be thin and would most likely snap or break with a small amount of weight.
