The choctopus44 by Routa Keebs. Prototype posted by badgers_are_rad.

The CHOCTOPUS44 is 44-key column staggered keyboard with a rotary encoder – SlightHeadache.

Github repo:

It was very much inspired by the rev41. My buddy who designed it found that he wanted a few more buttons. That's pretty much it. He bought the rev41 and used it daily. He mostly uses choc switches so wanted a choc board, he also wanted more switches. Thus choctopus44 – badgers_are_rad.
