Okay, I've finally "finished" mine, for now. I changed a few details, and added a few, just to make it mine. And to have a few "real" bits and bobs on it rather than have the whole thing be PLA. Well, aside from the steel rod running through the center.
Emitter detail is from a little roller bearing I had, with a thin brass ring beneath it. I think it's from a camera lens. I've got so many parts/greeblie bags and boxes sometimes I forget what came from where!
I drilled and tapped both ends of the rod and threaded the top and bottom parts so no glue is needed at all. Added some small chrome 3mm LED bezels at the little round detail areas at the top of the main body. For a minute I had chromed slot car hubs and Swarovski rhinestones like on an old Star Trek Communicator, and while they looked pretty good, they were just a tad too bling for my taste!
Painted gloss black after priming, then sprayed some Alclad "Duraluminum". Then took a silver leafing pen to it, then gave it some light washes of brown and black.
Put all the parts back on the lathe and lightly polished/burnished the finish. And here's how it looks now! Kinda reminds me of galvanized steel. And I'm not totally sure I like it, but I like it enough to leave it alone for awhile!
One thing I still want to do is cover the "exclamation mark" on the switch with something a little different.
And after looking at the pics one more time, I can see a few areas that could've used a bit more sanding/prep before I started painting! Dangit, I hate print lines!!
