Hot-Swapable 3.5" or 2.5" Hard Disk Cabinet for Nano Pi M4 (optional)

I made this modular hard disk cabinet for my nano pi m4 micro processor to build a NAS (network attached storage). The 3.5" hard disk cabinet can obviously be used together with other systems.

The design supports hot swapping drives without loosening screws. It is held in place with the sata data and power connector. The cables are secured in place with a simple plastic piece that is screwed on using 2x M4 screws. I'm using these sata cables, but you can use any cables you want so long they fit in the designed opening of the case.

Each cabinet is stackable and is held secure by a small clip. You can easily stack any number of hard drives with this design. You can also use screws if you don't want to use the clips.

A small arm extension is provided so that the nano pi m4 can be mounted on the side together with the hard drives. It is not very sturdy and I might upload a redesign later if I find it insufficient.

If you want to modify the design in some way, I'll supply a Fusion 360 link here: https://a360.co/3bfAgbK NOTE: The hdd drive cabinet has to be mirrored before printing. I accidently put the cable holes in the wrong corner. A simple mirror in the slicer fixes this. This is only the case if you use the model from fusion 360. The provided stls DO NOT need to be flipped.

Update 28 September 2020

• Add 2.5" version
• Add an alternative version of the hdd case (both for 2.5" and 3.5") with a more open design where the sata cables connect. It is designed to fit an alternative design of the sata cable (design B of the sata cables in images).
