I printed the shade with a 0.8mm nozzle at 0.4mm layer height. I didn't get any of the wobble shown in the other photos, it's unclear why. I did notice that spiral vase mode creates seams on layer change with 0.6 and 0.8mm nozzles in PrusaSlicer 2.3. I used a candelabra sized bulb, and may play around with positioning a bit (the bulb seemed a bit too low) and I'm not fully happy with the diffusion effects yet. (edited)
