Ikea Tertial translucent lamp shade for vasemode (drawing incl.)

I bought a Tertial lamp, but at night it creates a brightly lit spot with deep shadows, making me uncomfortable. So I designed a replacement lamp shade and printed it from a translucent material, so it lights the rest of the room too without being too bright to have it in my periferal vision.

I like the original design and want to keep the same overall shape, but it seemed too plain (as it is otherwise just a piece of plastic), so I decorated it slightly with wide ridges. Hopefully you'll like it as much as I do :-)

Printing

• Use vase mode (Spiralize in Cura)
• Put it the narrow side to the bed (it shoud be cup-like)
• Bottom layers: make sure the bottom is at least 0.8 mm thick
• Material and perimeter width: use something temperature-resistant and translucent.
  • I used natural-colored ASA, 0.8 mm thick walls (this is the photographed version)
  • Originally I wanted to use 1.2mm of natural ABS+, but run out of material (ABS is white, ASA is slightly yellow)
  • I wouldn't use PLA as the part is quite close to the source of heat (LEDs and the built-in power converter in the bulb)
  • PETG will work, but it is much more transparent: unless you print very thin wall in opaque material or just accept some glare. Colored transparent material might create an interesting effects.

Drawing

SolveSpace drawing is attached. Note: SolveSpace likes to run out of memory and crash when exporting a rounded geometry into STL: if you encounter issues in export, go into configuration and set: 

• export chord tolerance: 0.05 (higher means less memory)
• export max piecewise linear segments: 200 (lower means less memory)

and try again. In case issues repeats, change the numbers further as indicated.
