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

thingiverse

I built this modular hard drive enclosure for my nano pi m4 microprocessor to create a NAS (network attached storage) system. The 3.5" hard drive case can be easily combined with other systems. The design allows for hot-swapping drives without loosening screws, secured in place by the SATA data and power connector. I used [these](https://www.aliexpress.com/item/32884159478.html?spm=a2g0s.9042311.0.0.613b4c4dr9Ks1m) SATA cables, but you can use any cables that fit in the designed opening of the case. Each enclosure is stackable and secured by a small clip, allowing for easy stacking of multiple hard drives. Alternatively, screws can be used for added security. A small arm extension is provided to mount the nano pi m4 on the side along with the hard drives. While it's not extremely sturdy, I may update the design later if needed. If you want to modify the design, I'll provide a Fusion 360 link here: https://a360.co/3bfAgbK. Note that the HDD drive enclosure needs to be mirrored before printing due to an error in cable hole placement. A simple mirror in the slicer will fix this issue, but only if you use the model from Fusion 360. The provided STLs do not require flipping.

This new design is compatible with both 2.5" and 3.5" hard drives, as well as an alternative SATA cable design (SATA Cable Design B).
