Functional as in it technically works or that its comfortable and realistic to use?
Mx spacing is 19.05mmx19.05mm. Choc spacing is typically 18mmx17mm. And this is 16.5mmx16.5mm? Maybe its just your hands but those appear even smaller than that.
Yup, I currently have v, z, and q on combos.
You can also check my current keymap in the repo I linked above (in the example_keymaps directory).
I've been using this layout exclusively for a few months now, the initial learning curve was actually not that steep, since I had been on the Aptmak layout for a while before reducing it a bit to this state.
It's minimal choc spacing (while not cutting off stuff from the switches). To be honest I didn't expect to be able to work so well with it but here we are :D
How are the keycaps 3d printed, Is it FDM, SLA or something else?
Also when you do combos to make lets say Q do you use one finger inbetween the keys or two fingers?
