Microlab 2 - Mini Modular Home Server Rack

Microlab 2 — Modular 3D-Printable Mini Homelab

Microlab 2 is a fully modular, open-source mini-rack system designed for makers, homelab enthusiasts, and anyone who wants a compact, customizable workspace for electronics or servers.
Unlike common 10″ racks, Microlab 2 is:

• Compact & Square – Small footprint, flexible orientation.
• Fully Modular – Columns, caps, trays, and panels snap together with M3 screws or magnets.
• 100% 3D-Printable – Print the entire project with just a couple of PLA rolls.
• Open & Hackable – Build trays and panels for Raspberry Pi, SATA drives, fans, screens, buttons, switches, and more.

Key Features

• Scalable frame: Start with 6U and extend vertically as needed.
• Universal panel standard: Any panel or tray can be mounted on any side.
• Cooling options: Perforated panels, magnetic fan mounts, and vertical airflow support.
• Accessory ecosystem: Mini-trays for SBCs and 2.5″ drives, panels for keystones, switches, rotary encoders, and displays up to 7″.
• Magnetic or screw-mounted side panels for quick swaps.

Printing & Assembly

• Print the columns, caps, and trays in PLA or PETG.
• Use standard M3 screws and nuts (optional 8×3 mm magnets for tool-less panels).
• All files are modular — you only print what you need.

Materials

• M3x10 or M3x12 screws & nuts
  • Minimum: ~32 pairs (all magnetic panels)
  • Full 6U build: ~112 pairs
  • Large setups (e.g., 6U+4U extension): ~160–180 pairs
• Optional: 8×3 mm magnets (4 per 1U panel) for magnetic mounting

Tip: Glue the magnets and let the adhesive dry before attaching panels. Make sure all magnets share the same polarity for maximum flexibility.

Example Use Cases

• Raspberry Pi clusters or NAS builds
• Compact home servers and firewalls
• Network switch + mini PC combos
• Sensor dashboards, HMI, or DIY control panels
