I dug in my parts bin and came up with a nice power switch for the alt delete. Its a panel mount switch with a nice nut on the back to screw it in.
However, when I threw it in the 3d model, it just looked dumb. It stuck up way too far, blocked the view to the LED display and the buttons.
So, I decided to mount it flush with the top of the case. I think it will look and function much better.
This of course meant that I couldn't just use the switch's included mounting nut sadly. So, I had to design a mounting bracket to hold the switch to the top plate.
I just threw this together to show an example of what goes into designing this thing.
