I just got one too (eBay shop)... here's a pair of AT3032s
While the mics are close they don't touch and are wedged tight in place when you close the lid. The box is a lot heavier than I was expecting, good for protection, bad for weight
If you are concerned about the mics clashing in this model you could put a piece of tissue-box cardboard between them, though I can't see this is necessary.
FYI: The AT3032 mics are 21 mm (0.83") in diameter
