The shoulder buttons work fine physically, but I want to change the design to be more comfortable and easier to use.

The lower buttons should go around the corner and and have a small slide where you can rest your fingers in.
The upper buttons should have a small (smooth) lip which should make it easier to feel and press them.
I've made some small models using FreeCAD how I can imagine them and sent them to the designers.
It's pretty ugly, but it's just meant to be a small dummy to show the way I'd like to have them - the designers job will be to make them look and feel good (... and I've never done any CAD before
