Pi Zero & Pi Zero W Expandable Cluster Rack

thingiverse

I designed a modular Pi Zero cluster rack that can be easily expanded to accommodate multiple units. To assemble this project, I used M2.5 nuts for the screws, which can also be replaced with metal fasteners if desired. A new version of the design is currently in development, featuring side walls and mounting points for 30mm and 40mm fans. The base plate has a notch to fit snugly onto a 1mm thick M2.5 nut, while the extender bolts have a depth of 4mm to ensure secure attachment. Additionally, the bottom plate features a 0.5mm standoff to facilitate easy mounting. Print Settings: Printer: Custom Rafts: No Supports: No Resolution: 0.1 Infill: 25 Notes: I've discovered that printing with an M2.5 screw at 0.1 layer height yields the best results. Furthermore, chasing the threads of an M2.5 bolt and metal nut pair can significantly simplify assembly.
