I just got my hands on an AI printer and have been practicing for two days. This is my first project—a simple toothpick holder. I printed it four times because I didn't know how to set the wall thickness. I made the curved corners of the model too small, so they're not very noticeable. I think I'll need to add some supports to the bottom of the box, as it's slightly concave. I modified the model multiple times before finally succeeding.
