If there’s any small gap left when it’s screwed together it could be a nitroglycerin tablet holder

That's the first thing I thought of when I saw this.
I don't know what it is for sure but I bet it'd work great as a pill crusher.
maybe perhaps it's a pair of caps for sensitive equipment, like some coaxial cable termination. these things can get expensive
My wild guess would be two end stops for pipes. One external and internally treaded for the same diameter.
That's what they are! I have a box full of leftover parts from years of home repairs, and I frequently store caps of opposite genders screwed together like this.
Could be a rosin pre-press mold.
This is almost what it is. They come in lots of shapes and sizes. This one is probably for hash coins. Seems too small for a puck for a rosin forge, and hash is commonly sold in pressed coins.
Yes, I think your right. I used a pre-press of similar diameter for a very small setup but now that I think about it, it had a chamber in the top piece like this: https://files.catbox.moe/c4tw63.jpg
Good call.
This thing is threaded though, which would be counter productive to the pressing.
I don't think the threads would impact the pressing with this design; they are outside the inner chamber.
