I modeled mechanical switch keycaps in Onshape. I have no prior knowledge on pianos, so I had to research their size quite a bit, but I managed to piece together how I wanted it to have similar sizing as the DS6 standard. I am still unsure about how long and high the keys should be, but the dimensions right now look correct enough. I am still quite new to Onshape, so I had to remake the keys more than what I would like to admit, and so I am praying I don’t get flagged for inflating hours for only producing what is more or less a glorified rectangle
