I was looking for a good model of the Lombardi Trophy that I could customise to a fantasy football award for my league. I wasn't happy with what I found online so I tried making one myself. I found a picture with the dimentions of the real trophy and used it as guidelines for my model.
I did split the ball in two different parts. This makes it easier to print. Just glue the to parts together and slide the ball over the base.
I printed it in silver PLA and used some fine sanding paper and filler to smooth out the model. Then I gave it several coatings of chroom spray paint.
(The stl files don't include the text that you see on the model in the pictures. I left it blank so you can easily ad your own.)
