rack-10inch

A DIY 10-inch rack for homelab gear, inspired by Jeff Geerling's mini rack videos.

The frame is made of 20x20 aluminium extrusion. It is closed with laser-cut panels (rear, sides and bottom) and held together by 3D printed parts: corner supports, side corner connectors, side handles and fan supports. The rear panel holds the cooling fans, and a support inside the rack holds a power strip.

Commit convention

Commit messages follow:

type(scope): description

Type

• feat: new feature, new part or new export
• fix: bug or geometry fix
• docs: documentation only
• style: formatting, indentation, renaming, with no impact on logic or geometry
• refactor: restructuring code, schematic or FreeCAD tree without adding or fixing functionality
• perf: performance improvements
• test: adding or updating tests
• build: build system or dependency changes (platformio.ini, libraries)
• ci: continuous integration changes (workflows, actions)
• chore: other changes that do not modify the product itself

Scope

• ecad: schematic, PCB, electronic components
• mcad: 3D modelling, mechanics, exports (STEP, STL, DXF, 3MF)
• fw: embedded firmware
• doc: user or developer documentation
• repo: repository structure, scripts, configuration

Description

Short and imperative: "add status LED" rather than "added status LED". Descriptions are written in English.

Examples

feat(mcad): add side handle stl export
fix(mcad): adjust corner support clearance
refactor(mcad): reorganize side panel bodies in the tree
feat(fw): update demo code
build(fw): add FastLED dependency
chore(repo): ignore freecad backup files
docs(repo): add commit convention to the README
