Stacking Doughtnut Tower

I have a new nephew and wanted to make him something in my continued learning of 3D modelling. Here is the result! I am overall quite happy with how it turned out, but it took some work to get there. As many of you may know from printing experience, it can be very hard to print perfect shapes, such as spheres or, in this case, a doughtnut so my solution was to split the rings in half for the purpose of printing and glue them together afterwards. This plan worked out very well. I am not the craftiest, so my seams could likely be better looking. All in all was a simple, fun project.
