The mesh is a bit noisy, but you can barely notice it even with the super shiny filament and big print size. I did not show the supported side in the video because it turned out a bit ugly. Splitting the model and then gluing the prints together might be better.
Do you know how the other shapes in the video are called? I'll upload them when I figured out the names and cleaned up the meshes.
filament:
prusament royal blue
