# 3D Printed NAS — 6-Bay ZimaBoard Home Server

[<img src="/Images/3D-Printed-NAS_Thumbnail.jpg">](https://youtu.be/NXIu-B52WPU)

A custom 3D printed NAS enclosure for the ZimaBoard single board server, featuring a custom power adapter PCB, tool-less drive trays, and a modular design that's easy to build and maintain.

## Specs

| Feature | Detail |
|---------|--------|
| **Drive Bays** | 6× 3.5" SATA (tool-less caddies) |
| **SBC** | ZimaBoard 832 |
| **SATA Expansion** | 4-port PCIe SATA card via 90° riser |
| **Cooling** | 2× Noctua 80mm (rear exhaust) + 2× Noctua 40×10mm (drive bay intake) |
| **Power** | Custom PCB adapter — dual 5V/12V rails from a single multi-output PSU |
| **Enclosure** | Fully 3D printed (14 parts), M3/M6 fastener assembly with heat-set inserts |
| **Approximate Dimensions** | Compact desktop tower (see CAD files for exact measurements) |

## Bill of Materials — Quick Overview

See [BOM.csv](BOM.csv) for the full consolidated parts list. Estimated total cost: **~$250–350 USD** depending on drive selection and region.

**Key Components:**
- 1× ZimaBoard 832
- 1× 4-port SATA PCIe expansion card + 90° riser cable
- 1× Multi-output PSU (5V 10A / 12V 12A)
- 1× Custom power adapter PCB ([order assembled](https://ocrlab.myshopify.com) or fabricate from Gerbers)
- 2× Noctua NF-R8 redux 80mm fans
- 2× Noctua NF-A4x10 FLX 40mm fans
- 72× M3 heat-set inserts + M3 screws
- 6× M6 threaded rods + nuts + nylon washers
- 6× SATA 22-pin male-to-female extender cables
- 2× Molex IDE to 3× SATA power splitter cables

## Required Tools

- 3D printer (FDM, 220×220mm+ bed recommended)
- Soldering iron with heat-set insert tip
- Hex driver set (M3, M6)
- Wire strippers / crimping tool (for PSU wiring)

## What's Missing (Help Wanted)

The following files would significantly improve this project but require access to the original design tools:

- [ ] **STEP files** — Neutral CAD format export from Fusion 360 (enables editing in FreeCAD, SolidWorks, Onshape)
- [ ] **Schematic PDF/SVG** — Circuit diagram for the power adapter PCB
- [ ] **PCB source files** — KiCad or EasyEDA project for the power adapter
- [ ] **Wiring diagram** — Full interconnect diagram (PSU → PCB → ZimaBoard → SATA card → fans)
- [ ] **Generic 3MF plate file** — Non-Bambu-specific version for PrusaSlicer/Cura users
