Lab Rax is a fully 3D printable, modular 10-inch server rack for homelabs. Perfect for Raspberry Pi setups, mini PCs, and networking gear, this DIY rack is cost-effective, easy to assemble, and highly customizable. 

This is an adapted version of my original Lab Rax project, which used brass inserts. This version has been modified to only use standard M6 or #10-32 button head screws and M6 or #10-32 nuts for assembly.

Alternate Configuration Options

This version assembles in the same way as the original, but screws go in from the opposite side (nuts on the inside in the hexagon cavities). The nuts need to be pressed into the cavities and may require a little force, this is by design so that they don't fall out when assembling the rack.

The handles, feet and all panels are compatible with the original version. Only the 12 edges are different.
