[Case] Enhancement idea: add guided holes to reach buttons without disassembly

[mcarbonne]

I received my "HomeButtons" today, a nicely built product !

I had an idea to improve the back plate design: add guides holes to reach reset and boot buttons:

Note: this is for illustration purpose only, I did not check dimensional accuracy at all.

Also, I noticed that step and STL files on github aren't up to date. I would be nice if you upload the last revision :pray:

Not needed, since the latest case version is much easier to open.
