Converted to OBJ in Blender, then fixed and exported to 3MF in Orca Slicer. My AY Ryu hasn't arrived yet so can't test compatibility with that figure, but 270% scale (about 13cm height for Level 1, which roughly matches the size of it on the boxart, but smaller than ingame) seems to work, the thick handle is about 4.5mm diameter. I printed Levels 1 and 3 on my Neptune 4 at 60mm/s, 0.15mm layer height, 100% infill density, tree supports, and laid flat on the bed. The prints feel sturdy but the side facing the bed is ugly, stick to Level 1 if you're not printing with resin.
