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
