I own an original and thought to share the design with you. I've added two variants of fitting (GU10 and E14) also I've mirrored the base so you can choose if you want to show the bed structure in your print/lamp or the top side. Mirrored version is with the bedstructure visible.

the print requires:

20x the ‘fin’ named: tjalle
1x base: tjalle gu10 final
1x top: tjalle top final

I printed the base and top solid and the fins with 20% filling
you can ofcourse use all kinds of materials and precision. really curious what kind of translucent materials this can be printed with! maybe some multiple coloured fins.

happy printing!
