Finally, I needed a way to connect my keyboard and device, so they could be adjusted if necessary. 

Why do I need to adjust them? Because I like to make things difficult.

The E-Waste Gods had graced me with a Gen-1 Apple Magic Keyboard. I made these parts to securely affix it to the hilt, using Cam-levered 5mm "go-pro" compatible bolts. It took a lot of trial and error to get the mounts to fit the keyboard properly, but it works just as well as I'd hoped.
