My new custom WASD keycaps with NEO2 legends have arrived. I wanted nicely readable legends for the layers I used most, not for all as the predesigned caps offered. I also had problems with the color coding, which emphasized the wrong layers.
At the beginning, I had plans to turn my own handwriting into letters, but that proved too much of a task for the time I had, so I just went with stock symbols and Comic Sans.
I also considered having black keycaps, but after I studied up on the finer points of laser printing on dark base colors - bright colors require a white underprint -, I decided to go with colors on wite for crisp outlines.
All in all I am very happy with the result. My children begged me to give them a chance, so I hand wrote QWERTZ legends on the sides.
I got them made at WASD Keyboards. They have a prepared design file for 104 key ISO (and some more layouts) you can use. My board carries 108 keys, but I don't mind the programmable keys looking different than the main set.
Quality wise, they look good, and I like the slightly rough feel. "Side print" is Qwerty in my own hand, with acrylic marker, for the kids. Profile is Cherry.
