Differences:

• Made various cutouts larger to make access to reset button/power switches easier.
• Added a slight cutout along the inner walls to keep keycaps from scraping against them.
• Made the body slightly deeper (2mm) as well as removed the screw posts for cover to accomodate larger batteries.

I found that the original model had a rather troublesome mesh error near outer thumb key that blocked all of my initial attempts to extrude over them. I had to delete all surrounding faces and recreate them. Hopefully it's fine now, at the very least I was able to extrude/fillet everything that was needed.

The timeline is a mess I know. I labeled one particular group of features that you can suppress if you want to bring back the cover screw posts.
