Lampshade nut

I bought a used lamp of that style with like five lightbulbs on bendable mounts. It was missing a couple of the shades and nuts though, so I decided to make them myself. Maybe someone else could find this useful.

I posted the Fusion file so others can tweak it. I'm surprised it worked first try, I didn't know the right way to measure it and just noted that there were 2 threads per 5 mm, but it fits perfectly. Unfortunately, I don't have any info on who made the lamp, so you may have to tweak it yourself.

Feel free to give feedback of any kind! I might have time to make some edits if asked.
