The first model which I made is lampshade_conical.scad. That was the easier one. But I wanted to have the lampshade more curved, so I did the second model, lampshade_curved.scad.

Configuration of the lampshade_conical is pretty simple, and the second is a little bit complex - you need to play with curved_factor to find a proper design and height.

And btw. I lost the nut for the lampshade.

My first models contain nuts as part of lampshade, but it wasn't a good design, so I made a separate ./nut.scad again - fully customizable.

Thanks to decision to separate lampshade and nut (the original set up of the lamp btw.) I'm fully flexible.

I wish you a lot of fun with modeling (and printing).

how to install dependencies for nut?

I use threadlib

you need to install (download or checkout) to the OpenSCAD library folder those repositories:
