Hanging Raspberry Pi Case - Aluminum Extrusion

I really liked the [original design](https://www.thingiverse.com/thing:604915) by [walter](https://www.thingiverse.com/walter/about), but wanted to mount the case on my Prusa MK3. I took inspiration from [thing 2843889](https://www.thingiverse.com/thing:2843889) by [Coopey](https://www.thingiverse.com/Coopey/about) to add a hook to the case that allows it to hang from 3030 aluminum extrusion. It fits perfectly hanging on the side of my printer. It's very sturdy, and sits nice and flat.
