Well, I chose KAM because of the large surface.
Sadly I had to work with the KAT template that's why the legends are so tight...
Keep in mind that this a prototype
I thought about KAT R3 only (to keep the "uniform" look), but I'll have to check the top surface.
IIRC overall dye-sub on KAT isn't easy because how dug the keycap is.
I'm still working on the project and trying to find solutions with Keyreative tho!
