Only changes have been to remove the outer most column and so move from 40 keys to 36, plus a change of keycaps and some angled risers for the keycaps on both top and bottom rows.
As to the request for an explanation, it’s a 36 key, ortholinear, staggered and splayed split board.
36 keys - should be obvious Ortholinear - the keys are in line on the vertical axis, unlike a regular keyboard that has an offset between rows Staggered - the pinky column is set lower that the middle finger column, as my pinky is shorter and can’t stretch as far Splayed - if you naturally open an close a fist, your fingers don’t stay together when you open your fist, but rather they splay outwards. The keyboard follows that natural splay.
Other than that, it’s using QMK, and has 3 layers. I’ve not bothered mapping F keys, as I don’t use them. So layer 1 is regular alpha, layer 2 has numbers (or with shift has symbols), layer 3 has directional keys.
Also using home row mods for Command, Control, Option (work computer is a Mac).
