I really just have general threads for prop categories.
I've got a lightsaber thread, a blaster thread and an "other" thread.
Just search "Dann's (insert lightsaber, blaster or other here) thread", and you should be able to find them relatively easily.
I model and print a LOT of my own parts. After I discovered the scope used on the SE-14R, I modeled it, and it's gone through lots of iterations. I've sold a couple replicas, but haven't done a proper sale thread for it.
I've also got a bunch of scopes for Fett, Evazan/Chewie and Ponda Baba blasters, many of which are Frankenscopes. I've modeled different objective bells, and used the lathe to modify vintage 4x15 scopes so that they can accept either real or printed 4x20 objectives, etc.
I'm planning to open an Etsy store to list them for sale (as well as some other parts I've modeled), but I may put a few in the JY first.
I'm just slow-going with it, so it's taking longer than I wanted!
