Printed this a while ago, 26 pieces resized to 8cm high: https://www.thingiverse.com/make:479810
Now printed in original size for our dinner table light, fits perfectly like it was made for it, I had to print rings with hole to glue and mount it.
Printed 3 and have to print another 3, takes 8 hours to print, you can see the original shades in the picture.
Again, thanks for this upload! Really happy with it.
