It's not exactly art, but I recently made this:

It's the sword of the creator from Fire Emblem: Three Houses

It took about a kilogram of filament to print, and then about a week of gluing, painting, weathering, and aging it. First I scratched the hell out of it with a dremel to make the cuts and scars in the sword blade, then I painted with an off-white base coat and a few washes of browns, greys, and yellows to give it that aged bone look. The pictures I took aren't the greatest, but I'm super proud of it and I think it looks great.
