Low cost & Compact 12-Drive NAS case

thingiverse

I designed this over a year ago and have been using it daily ever since, let me know if there are any problems with the design and I'll look into it! This is designed for 12x3.5" hard drives and is semi-hot swappable, taking about two minutes to swap a drive. This design combines 3D printing with laser cutting, requiring a laser cutter and a 3D printer to complete. I designed this NAS to be as small as possible, using a 240W low-profile power supply combined with a Pico-Power power supply. A standard power supply won't fit with the lid on! This NAS case costs around $40 and takes an afternoon to complete. All laser-cut parts can be friction-fitted but it's recommended to screw them together. All laser-cut parts should be cut from 6mm wood, MDF or acrylic; I recommend using MDF as it's sturdy and flat. **Dimensions:** 272x455x248mm **Laser-cut parts:** Front Panel: 1 Back Panel: 1 Bottom Panel: 1 Middle Panel: 1 Top Panel: 1 Center Panel: 1 Side Panel: 2 **3D-printed parts list:** PSU Retainer: 2 90-Degree Fasteners: 12 HDD Rail: 2 for each HDD HDD Rail Holder: 1 for each HDD (only required for one side of the middle row) HDD Rail Holder Nut: 1 for each HDD **Screws:** 5.0mmx12mm plastic screw: 16 6-32: 6 for each HDD (~8mm length is recommended) M3x12mm: 28 (3 for every HDD, outer row for the rail holder) M3x14mm: 3 for each HDD (center row for the rail holder) M3-Nut: 28 (6 for each HDD) M3x16mm: Replaces one of the M3x12 screws for the HDD and locks the sliding of the hard drive cage (optional) **Purchased parts:** 1400x1000mm MDF: 1 ($10) 120mm Fans: 4 ($15) 12V-240W PSU: 1 (can be found on eBay for ~$20) Pico-Power Power Supply: 1 (can be found on eBay for ~$10-$50)
