For my 3D model inspiration, I chose “Mid Century Modern Metal Sculpture Art Abstract Simple Contemporary Decor Modernist” by Petrykowski Artworks. The sculpture reminds of a iteration of the Olympic logo. They stack vertically at a tilt which i think makes a cool 3D model.

That looks like a good choice for Tinkercad.
