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 swapabale", it takes ~2minutes to swap a drive

This design mixes 3D-printing with Laser cutting, it requires a laser cutter and 3D printer to be completed.

I designed this NAS to be as small as possible so it uses a 240W low profile power supply, combined with a "Pico-Power" power supply. A standard power supply will not fit with the lid on!

This NAS case costs ~40USD and takes a an afternoon to complete.
All laser cut parts can be friction fitted but it is recommended to screw it together.

All laser cut parts should be cut from 6mm wood, MDF or acrylic. I recommend MDF, its sturdy and flat.
