Case is Bubbleology's fantastic 3dp design (closed source).
Alphas are MT3 (2048 Katakana), thumbs 3dp DES by Pseudoku (mjf print from jlc).
I really enjoy the board, but the thumbs are waaaay too tucky for me 😅 I basically can't reach the 1.25u ones without significant discomfort / moving my entire hand. Good thing it's got a few too many keys for my taste so i can just ignore those thumbs :D
Peek inside:
Do the thumb keys do the h-line and f-line modifiers? I’ve never seen a katakana board in action.
it’s just the legends, i’m not typing katakana with it 😅
