Your keyboard looks awesome, and appears to follow the shape I mentioned earlier (almost like a heart shape). Now it’s made and you’ve been using it for a while, do you think it might have been worth adding a few more keys, perhaps above the 9 and 8 and one to the left of each them? Or maybe even a single one where it feels most natural?
How did you find what the perfect fitting is for you? Use paper? Or maybe keys cut out of paper with a bit of sticky tape on the back so you could find the perfect position? I think I’d like to try making one one day! Are there any sites dedicated to this specific topic? (If not, why not create one!?)
This could also be an amazing business opportunity: custom keyboards made to fit your hands! You send out a mould or print kit, people could take moulds and then send them back, and then you make a perfect-fit keyboard for them! 
I wonder if anyone is already doing it?
