So Nautilus Nightmares won’t fit on a MiniVan? Ah, I see, at least the 1.5u Enter is missing. Meh. And yes, this really looks like a boycott to me since—at least from my point of view—the MiniVan one of the best and most popular 40% keyboards.
So with having an IMHO worsening last-minute-change to the colors compared to the IC and with no MiniVan support, I’m thinking about cancelling my Nautilus Nightmare order…
Then again, I have some other 40% keyboards where this keycap set seems to fit, also colorwise: a gray Daisy HHKB and a brass JD40, both with 1.75u Enter key and overall 0.25u wider than the MiniVan. (I also have a KeyHive Nightmare 50% kit, but the case is orange and surely doesn’t fit to NN colorwise—even despite the name does fit. 
)
And most of my MiniVans already have their dedicated keycap set (Catalyst aluminium case with GMK Paperwork, black case with GMK SkIIdata) or I’m waiting for their planned keycap set (purple case gets SA Laser, white case gets KAT Milkshake)…
