PiNAS is a 3D printed compact NAS enclosure based on Raspberry Pi and up to two SATA HDD/SSD units connected to the Raspberry Pi via SATA to USB converter.
Software-wise it runs on Raspbian and Samba/FTP/anything you like. Power supply can be provided using a 12V 5A external PSU that will power the +12V lines of HDD/SSD drives. +5V power supply can be provided using a small buck converter such as the DC DC Step Down MP1584 that can provide up to 3A of current, enough to power the Raspberry Pi and the two disk units.
All parts should be printed using:
- PLA filament
- 3 walls
- 0.1mm layer height
- 15% infill
- print plate adhesion raft if needed
Use:
- 'Raspberry Pi 2 plate.stl' for Raspberry Pi 2
- 'Raspberry Pi 4 plate.stl' for Raspberry Pi 4

PiNAS is powered by a +12V 5A power supply. Two DC/DC buck converters are used to:
- provide +5v to power the Raspberry Pi
- provide +5v to power the two HDD units and to inject enough current to the USB/SATA converters. The Raspberry Pi can provide at most a few 100s mA per port
