# Assembly Overview
This document provides a high-level assembly reference for the 3D Printed NAS. For detailed step-by-step instructions with photos, see the [Instructables guide](https://www.instructables.com/3D-Printed-Home-Server-6-Bay-ZimaBoard-NAS/) or the [build video](https://youtu.be/NXIu-B52WPU).
## Before You Start
- [ ] All parts printed (see [PRINT_SETTINGS.md](PRINT_SETTINGS.md) for quantities and settings)
- [ ] All components sourced (see [BOM.csv](BOM.csv))
- [ ] Heat-set inserts installed in all structural parts (72× M3 inserts)
- [ ] Soldering iron, hex drivers (M3, M6), and wire tools on hand
## Assembly Order
### 1. Install Heat-Set Inserts
Insert all 72× M3 heat-set inserts into the structural parts using a soldering iron with a heat-set tip. Parts requiring inserts:
- Base
- Side plate L / Side plate R
- Brace
- Back fan housing
- Zima support
### 2. Assemble the Frame
1. Attach **Side plate L** and **Side plate R** to the **Base** using M3×10-12mm countersunk screws
2. Install the **Brace** between the side plates
3. Mount the **Back fan housing** to the rear
4. Install the **Front grill**
5. Install the **Zima support** bracket
6. Install the **PCIe card support**
Use **M6 threaded rods** with **M6 hex nuts** and **M6 nylon washers** for the drive bay rail system.
### 3. Mount Electronics
1. Mount the **ZimaBoard 832** onto the Zima support bracket
2. Connect the **PCIe SATA expansion card** via the 90° riser cable
3. Secure the **power adapter PCB** in its designated location
### 4. Wire Power
> **Important:** Double-check all connections before powering on. The power adapter PCB handles dual 5V/12V rails at significant current.
**Power adapter PCB connectors:**
| Connector | Pins | Function |
|-----------|------|----------|
| PSU_IN | 3-pin terminal block | Power supply input (5V, 12V, GND) |
| ZIMA_PWR | 6-pin header | Power to ZimaBoard |
| ZIMA_IO | 14-pin header | ZimaBoard IO connection |
| POWER_SW | 4-pin header | Momentary power button |
| DRIVES_PWR1 | 4-pin Molex | Drive power rail 1 (drives 1–3) |
| DRIVES_PWR2 | 4-pin Molex | Drive power rail 2 (drives 4–6) |
| X1–X4 | 3-pin Molex | Fan headers (12V) |
**Wiring sequence:**
1. Connect the **PSU** output to the PCB's **PSU_IN** terminal block
2. Connect **ZIMA_PWR** and **ZIMA_IO** to the ZimaBoard using the ribbon/header cables
3. Connect the **power button** to **POWER_SW**
4. Connect **DRIVES_PWR1** and **DRIVES_PWR2** to SATA power splitters → drive extender cables
5. Connect fans to **X1–X4** headers
### 5. Install Drives
1. Slide each drive into a **Caddy**
2. Snap on the **Cover**
3. Insert assembled caddies into the **Slots** separated by **Separators**
4. Connect SATA data cables from drives to the PCIe SATA card
5. Connect SATA power via the extender cables
### 6. Install Covers
Attach in this order:
1. **Back IO** panel
2. **Back plate**
3. **Side cover**
4. **Top cover**
5. **Face plate** (front)
### 7. Power On and Configure
1. Connect power cable to the **Power Socket Inlet Module**
2. Press the **power button**
3. Access the ZimaBoard via network to configure your NAS OS (CasaOS, TrueNAS, OpenMediaVault, etc.)
## Safety Notes
- The power adapter PCB switches up to **40A across dual rails** using P-Channel MOSFETs. Verify all connections before first power-on.
- Use a multimeter to confirm correct voltage on the 5V and 12V rails before connecting the ZimaBoard.
- Ensure adequate ventilation — the 4-fan setup is designed for continuous operation.
- PTC resettable fuses on the PCB provide overcurrent protection, but they are not a substitute for correct wiring.
## Troubleshooting
| Issue | Check |
|-------|-------|
| No power | PSU_IN terminal connections, power button header, PSU switch |
| Drives not detected | SATA data cables seated, PCIe card in slot, riser cable connection |
| Overheating | Fan headers connected (X1–X4), fan direction (intake front, exhaust rear) |
| Drive caddy too tight/loose | Print tolerance — try ±0.1mm horizontal expansion in slicer instead of scaling |

# Print Settings
Recommended FDM print settings for the 3D Printed NAS enclosure. All parts are designed for standard FDM printers with a 220×220mm or larger bed.
## General Settings
| Parameter | Recommended |
|-----------|-------------|
| **Material** | PLA or PETG (PETG preferred for heat resistance near electronics) |
| **Layer Height** | 0.2mm |
| **Nozzle** | 0.4mm |
| **Infill** | See per-category settings below |
| **Wall Count** | 3–4 perimeters |
| **Top/Bottom Layers** | 4–5 layers |
| **Supports** | Generally not required (see exceptions below) |
## Per-Category Settings
### Structure (Base, Brace, Side Plates, Fan Housing, Zima Support, PCIe Support, Front Grill)
These are load-bearing parts that support the weight of the drives and ZimaBoard.
| Parameter | Recommended |
|-----------|-------------|
| **Infill** | 30–40% |
| **Pattern** | Grid or Gyroid |
| **Supports** | Not required |
| **Orientation** | Print flat on the largest face |
| **Notes** | The Base and Side Plates are the most structurally critical. Use PETG if possible. |
### Covers (Back IO, Back Plate, Face Plate, Side Cover, Top Cover)
Non-structural cosmetic panels. Lower infill is fine.
| Parameter | Recommended |
|-----------|-------------|
| **Infill** | 15–20% |
| **Pattern** | Grid or Gyroid |
| **Supports** | Not required |
| **Orientation** | Print flat, exterior face down for best surface finish |
| **Notes** | Face Plate is the most visible — use a higher quality profile if desired. |
### Drives (Caddy, Cover, Separator, Slot)
Tool-less drive tray system. The Caddy is the most printed part (6× needed).
| Parameter | Recommended |
|-----------|-------------|
| **Infill** | 25–30% |
| **Pattern** | Grid |
| **Supports** | Not required |
| **Orientation** | Print flat |
| **Notes** | Print a test caddy first to verify drive fitment before printing all 6. Tight tolerances — do not scale. |
## Part Quantities
| Part | Quantity |
|------|----------|
| Base | 1 |
| Brace | 1 |
| Back fan housing | 1 |
| Front grill | 1 |
| PCIe card support | 1 |
| Side plate L | 1 |
| Side plate R | 1 |
| Zima support | 1 |
| Back IO | 1 |
| Back plate | 1 |
| Face plate | 1 |
| Side cover | 1 |
| Top cover | 1 |
| Caddy | **6** |
| Cover (drive) | **6** |
| Separator | **5** |
| Slot | **6** |
**Total print count: ~34 parts**
## Bambu Lab Users
A pre-arranged plate file is included at `Enclosure/CAD/3MF/3D Printed NAS _Bambu Plates.3mf` for Bambu Studio.
> **Note:** This plate file uses Bambu Studio's proprietary 3MF extensions and may not open correctly in PrusaSlicer or Cura. Use the individual STL or 3MF files from the `STL/` or `3MF/` subfolders instead.
## Filament Estimate
Approximately **800g–1.2kg** of filament total, depending on infill and part count. Budget 2 rolls.

# 3D Printed NAS — 6-Bay ZimaBoard Home Server
[<img src="/Images/3D-Printed-NAS_Thumbnail.jpg">](https://youtu.be/NXIu-B52WPU)
I was juggling too many small SSDs for backups, so I set out to build something more permanent.
In this video, I walk you through the design and build of a custom NAS powered by the ZimaBoard — complete with a custom power adapter PCB and tool less drive trays.
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.
Build instructions → [Instructables](https://www.instructables.com/3D-Printed-Home-Server-6-Bay-ZimaBoard-NAS/)
## 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) |
