Basic Raspberry PI NAS Box/Case

The case consists of different layers, designed to be hold together by a rubber band or stacked loosely on top of each other

I wanted the design to be expandable so I can add or remove layers if I change my configuration or buy another pi with only one ssd :)

The top layer is designed to support a Noctua NF-A4x20 fan.

Layers:
- toplayer/lid with fan cutout on top
- middle Raspi layer with IO cutouts
- middle ssd layer with holes at the bottom
- bottom ssd layer with holes at the back

Bottom layer is not technically not required but looks nicer and middle layer can be stacked in any combination and number of times as you please

**Consider this a rough draft**, I'm using a older version from an earlier draft myself so please be careful before printing. The modelling is kind of bad because I started without a plan and used this as an opportunity to relearn modelling in Blender but it works :)

Warnings:
- layers are only loosely stacked on top of each other, I recomm
