Got the one from an SMOK alien and my spouse dropped it and finally did something that I couldn’t fix. The top cap is (for some reason) not clasping shut and I can’t find anything on it how to fix it. It doesn’t look like its misalignment,
Nor can I find a replacement top cap online
Anyone ever run into this?
I had a similar issue with my Baby Beast…had it in a cup holder on my bike, hit a bump…Baby Beast and mod went airborne.
Anyway, for me I ended up having to re-align the part that swivels on the cap. There’s a pin that was barely noticeable. If I remember right I pried the swivel piece up just a tad with a small screwdriver where the pin is. Realigned with the bottom clasp and used pliers to crimp it back together. Works good as new but YMMV. Good luck!
Replacement spouse? 
It’s barely aligned now, it does close, but barely, just the tip
and nah, 10 years down, infinite to go haha XD @Josephine_van_Rijn
Just get something that doesn’t have Smok written on it
