Not off the top of my head, but I can measure that for you.
On a side note-CloudTen still makes one, I have two (one for the classic and hybrid)
If you want a ‘manufactured’ case. (Although I do like how neatly everything fits and stacks up in this case)

Although I admit, I would never pay $70 for this case, I got both of mine for a about half off (20% off sale, and each time I had more than $20 off in in store credit from buying each volcano)
I just pulled the beasts down from their shelf to get a more accurate measurement for you, and for the hybrid specifically.
I wish there was a picture I could just send you, but I will opt for being as specific as I can. (First set of measurements explains exactly what the measurement is of and try’s to explain how I’m measuring it, the second simplified set bellow should make sense, and is the one you should use, but if it doesn’t see first set for explanation)
The smaller diameter (diameter of the base ‘puck’, which is underneath the slightly wider cone) is 7&1/4in
(or almost exactly 18cm)
And goes straight up for 1&3/4in (a little over 4.5cm (the little peg legs are the difference between 4cm and almost 5cm)
*The bottom of the cone of the volcano is wider, at 7.89in or almost exactly 20cm (19.8cm)
The cone is about 5&1/8in (or almost exactly 13cm) tall. (Note this is not the direct measurement against the side/slope of the device, just the vertical height from the flare of the cone, at the bottom, to the top, measured by putting something flat on top of the volcano to see where it’s height stops against the vertical measuring tape)
-With just under 2&1/2in top diameter (or almost exactly 6cm)
The total height, the combination of the come height and base height) is approximately 18cm
So in simplified form,
Base puck is 18cm (7.25”) in diameter and in between 4 to 5cm tall (approximately 1.6” to 1.9” -with and without the measurement of the legs included)
The cone that sits on top is 20cm (7.89”) in diameter and 13cm (5.125”) tall, with a taper to the top, which is 6cm (~2.5”) in diameter.
Total height of device measures roughly 18cm (or roughly, 7.25”)
So they’re ~7inch l*w*h measurements are fairly accurate (albeit without the specific measurements it’s much harder to tell where the cone tapers and how much)
If you need me to take any other measurements feel free to ask. (It’s not that big of a deal to pull the box with them back down) (I was also thinking it would almost be easier if the measurements where for a cross section of half/a quarter slice of the device/ in radius, making it easier to create the shape for one side and easily be able to mirror it)
Any ways, good luck in building, or finding, a case that works best for you!
