There are certainly many ways to design a circular lantern. In this design, I used sketching, rotation, extruding, and circular patterns. It makes a great entry-point 3D design project. Please scale it up or down to fit your preferences. A raft is needed because of the small contact surface on the printing bed.

Yes
