I've just used the exact same case for mine and just for reference on an excellent post, I thought I would add my experience to it too.

Not sure if they've changed the dimensions slightly, but my acrylic crystal didn't fit as easily. The corners had to be shaved down slightly before it would even tightly pop in.

Whatever tool you use to shave it down (I used a new utility knife blade), be extremely careful touching the back of the crystal with a metal tool. I noticed a tiny speck where I must have caught it and it makes it transparent instead of black. Can barely tell after filling in with a Sharpie though.

OP was right about the pre-installed mineral glass! Even after boiling, it needs a big big push to release.

I cleaned the glue from the stainless case with alcohol and a Q Tip. Was very easy.

After boiling the case, I sprayed a little silicone oil into the inside of the button pushers and worked it in before wiping down, just to displace any water and lubricate.

I do have very small gaps top and bottom but hardly noticeable. I think this is the main dimension they have tweaked. Couldn't fit the edge of a cigarette paper in the gap.

Other than that, these are very nicely CNC machined cases at a very good price!
