Fits my Ferris Sweep well

The flap inside of it is weird though and I'm not sure what its purpose is. Otherwise, a perfect fit. A nice coincidence seeing this on the shop when building this niche keyboard.

Check the dimensions before ordering

Despite the product description, the Ferris "base" variant does not fit, just barely too big to squeeze in. Oops, guess I should have compared the dimensions before ordering. That aside, it's a pretty nice case so can't really complain for the price.

Not enough space inside for a corne v3 5 row with case
