I just finished this fun little keeb which I based off the Hummingbird, but I made it hot swappable, dropped the pinkies down more, made the thumbs more reachy, and spaced it for Chosfox CFX keycaps (tighter than standard Choc spacing).

It has a top plate and sound-dampening silicone gasket, as well as foam on the backside of the PCB.

Everything is open sourced on my github
