Been thinking about the buttons a lot and to make it clear how much space and where it is I have for buttons I quickly mocked up it up:
The purple areas are block-outs of the free space, I’ll gradually populate it with custom buttons, already started with the red triangular:ish one on the thumb side. Haven’t modeled the rear part that the buttons pushes against yet.
Locked down the bottom panel of the throttle’s design, buttons etc won’t affect it and I’ve established the mounting points of the panels that connect to it so I decided to print it:
Fits like a glove, measure twice print once people.
