Printing: 

The pine cone lampshade was printed with only one perimeter. A modifier and a negative volume are included in Prusa Slicer project file to create a geometry that can be clamped in between the two lamp holder parts. 

Please see 3mf-file, for modifier stack and full parameter setup.

Assembly: 

First, the lamp socket was inserted into the middle part and secured with the locking ring. 

The pine cone lampshade was placed between the base and the middle part and fixed in place with a bayonet lock. 

If you need an extra diffusing shade, you can use the adapter of the twisted lantern shade.
