Lamy Logo Finial

This is a replacement finial for the Lamy Logo pen. I didn't like the slits in the original part (silver in the photos) or the extremely long post, so I made an end cap that works with a solid click similar to the Lamy Studio or Montblanc Noblesse. Just need to print it in a black, lol. Don't know why Lamy didn't just put a metal end cap like this on the pen to begin with.

The default finial simply unscrews. It's a non standard thread size, though I'm pretty sure its a 0.75mm pitch. (M8 is too small and M9 is too big.) The thread on the replacement works but its not perfect, so I've included the original fusion360 file if you want to try tweaking it some.
