I ended up printing the above design, and sadly due to the trigger location, its just uncomfortable and makes you reach abit much to hit the triggers. So I jotted down a quick idea for a new trigger design, this is far from the end result and needs alot of work to avoid the mounting screw locations. But this is just a general idea of what I'm going to try next, sadly getting these triggers right have been the biggest hang up on this design moving forward.

Once I get the triggers right, I can then work out the fastener and screw setup, as I want to avoid any on the face as much as possibly, and then final shaping.

The triggers shown below in blue are again just a quick idea to capture it on paper, I haven't even modified the base yet to accept them, or honed them to the point they wont interfere with the screws, yet go around them.

I'm also aiming to shave possibly 6mm of over all thickness in the case design as well to make it more sleek.

The last milestone to overcome after the triggers and fasteners is audio locations. I'm still wanting to add stereo speakers to this device, and hoping to work them into each side near the top.
