Printed perfectly at 150% in white PETG first try (vase mode, 50% speed). Esthetics is 10 out of 10. But assembly was terrible. The bottom part is OK but I think the top part (E27 holder) is the worst mechanism I've ever encountered out of all my MakerWorld downloads. There must be a way to make it easier, or maybe I'm too dumb. But the combined effects of screwing things on different directions and the small opening made it a 1hr long struggle. Next time I need to change the bulb I'll enroll my nephew with smaller hands. Still functionnal and really beautiful, thanks!
