Modular Filament Wall Rack – Clean, Expandable 3D Printed Spool Storage

🧵Keep your filament organized, accessible, and off your workspace with this modular wall-mounted spool storage system.

This system was designed to scale with your collection—add more brackets and rods as needed, and customize spacing based on your setup. I built this to clean up my printing area and keep everything within reach of my printer (running OctoPrint on a nearby Pi), and it’s made a huge difference.

🔧 Features

• Modular design – expand horizontally as your filament collection grows

• Clean wall mounting – uses integrated keyhole slots for easy install

• Removable rods – quickly swap or rearrange spools

• Universal compatibility – works with standard 1kg cardboard spools (ESUN shown)

• Compact & efficient – keeps spools organized without taking up bench space

• Strong + lightweight – reinforced bracket geometry for strength without wasting filament

🧩 Components

• Wall Bracket (Left/Right interchangeable)

• Spool Rod

• Wall Anchor

Each “bay” consists of 2 brackets + 1 rod.

🖨 Print Settings

• Material: PLA works great (PETG recommended for warmer environments like garages)

• Layer Height: 0.2mm

• Infill: 15–25% (Gyroid or Grid)

• Walls: 3–4 perimeters

• Supports: ❌ Not required

• Orientation:

  • Brackets: flat on back face

  • Rod: horizontal

🛠 Hardware / Installation

• Mount using screws into studs or drywall anchors

• Keyhole slots allow:

  • Easy alignment

  • Quick removal if needed

💡 Tip:
Install the brackets first, then drop in the rods after mounting.

📏 Sizing / Compatibility

• Designed around standard 1kg spools

• Works great with:

  • eSun

  • Hatchbox

  • Overture

  • Most cardboard/plastic spools

If you run oversized or specialty spools, spacing can easily be adjusted when mounting.

💡 Why I Made This

I was tired of filament stacking up everywhere and wanted something:

• Wall-mounted

• Expandable

• Clean looking

• Easy to access a single spool

This setup keeps everything visible, organized, and right next to my printer without cluttering the workspace.

🚀 Future Ideas

• Snap-in filament guides

• Enclosed drybox variant

• Label clips for spool identification
