Where: Miniature Chicago Bean model (custom arts/crafts model)

Hello, I was wondering if anybody knew where to get a smaller mock-up of the chicago bean? I need to make one for a project. I have no idea how I would make one or get the shape correct (just needs to look similar doesn't need to be high quality) or if theres a store that would help me do this? I looked online and couldn't find anything and there are no Chicago Bean balloons that I can find for a reasonable price Thanks!

PS: a friend suggested instead maybe doing a big blowup picture of the bean and setting it as a backdrop which would also work for my project, does anyone recommend an affordable good print shop to do this?
