NASpi : Raspberry Pi NAS

thingiverse

Greetings!I embarked on this personal project with the aim of setting up a NAS (built with a Raspberry Pi 3B+) and making use of many components I already had on hand.Here's what you'll need for this project:A Raspberry Pi (3B or newer)One or more 2.5" hard drives (less than 11mm thick)12 M4 nuts12 M4 screws of 16mm or less2 times the number of drives you want to install of M3 screws (e.g., 3 HDDs => 6 screws)SATA to USB cables for each hard driveA powered USB hub sufficient to power all the drivesOptional:An 80x15mm fan4 screws and nuts to attach the fan to the interior wall of the backplateHeat sinks for the Raspberry PiNon-slip pads to place underneath the caseNote:The fan is optional and can be installed only if you're configuring as I did (or more), meaning if you decide to print at least the HDD base and two HDD drawers.If you plan to install more drives, the design is modular enough to accommodate additional drives beyond the initial setup (3 HDDs). You'll just need to print more drawers (tiroirHdd.stl). However, the backplate and frontplate were modeled for 3 HDDs, so you'll need to modify them accordingly, ensuring you retain the mounts for attaching the fan.If you're using a Raspberry Pi other than the 3B+ I used, make sure to check the placement of the mounting holes to ensure compatibility.The Fusion360 files will be provided in the downloads in case you want to make modifications to the design.For the OS, I used Raspberry Pi OS (formerly Raspbian) with OpenMediaVault to manage the NAS function (you'll find plenty of tutorials online).You'll also find many tutorials for further customization, such as installing Plex Media Server and even connecting the NAS to your router so you can access it outside your local network (be sure to exercise caution when opening ports on your internet router).As I'm not a very experienced modeler (this is my first design with so many constraints and where everything must be precise), the design may undergo distortions during printing, so adjustments may be necessary afterward (it all depends on your printing quality and printer).It's possible that you might need shims to apply pressure on the Raspberry Pi, in my case, I apply slight pressure on the Ethernet and USB ports and pressure on the HDMI port. These shims can be adhered to the cover (raspiHat.stl). I won't provide my files with the shims since they were inaccurate for me, and I don't want to supply faulty files. Therefore, I leave it to you to model them, taking measurements with a caliper (using the depth gauge).To assemble it, you'll need to glue the parts together (sand before gluing for better efficacy), guides are present to ensure proper positioning. As for the nuts, you'll need to glue them into the hexagonal holes provided for this purpose. If they don't fit perfectly, you can heat the nuts with a lighter and insert them into the holes.
