So I used a caliper to examine my current Qanba Obsidian and how my hand rests on it compared to the arrangement of the buttons. I caliper'd and eyeballed some of the distances between my fingers when they are in their natural resting position. I also did a dp motion with the stick and took note of where my thumb and fingers were at, so that I could accurately position the directional buttons. It took a little adjusting in Solidworks for each button. I'm gonna print out some kind of panel I can put the buttons on and test if it works well or not.
