Logical Wall Mounted Spool Storage

I’ve been wanting a better way to organize my filament spools for ages — one that keeps them visible, tidy, expandable, and right on the wall where I can grab what I need without digging through bins or shelves.

What I ended up with is this fully 3D-printed, modular wall-mounted spool storage system. It’s snap-together, it’s expandable in all directions, and the spool trays actually collapse up into the wall assembly when I need my wall space back. It’s been a game changer in my workspace.

What This Is

This system is designed to hold standard 1 kg filament spools and let you build as much storage as you need without a bunch of screws, brackets, or bulky racks. The trays are printed parts that rotate up into their housings, creating a compact footprint while still being easy to access. The rail system makes it easy to keep multiple rows aligned and expandable.

It’s perfect for:

Print farms
Compact workshops
Maker spaces
Anyone who hates tangled filament and messy shelves

How It Works

Build the Walls
Snap the wall components together — they key into each other so you know everything is aligned properly.
Assemble the Trays
Each tray part has a keyed rotation so it sits square in the wall assembly and can pivot up or down smoothly.
Mount to Rails
Slide the assembled trays onto the rail system. You can add more rails and spacers to widen or stack more rows.
Collapse for Space
Want the wall back? Just rotate the trays upward flush against the wall rails.

This system isn’t locked into any particular number of spools — you add as many as you like by linking rails and adding spacers.

Printing Notes

As with most of my functional designs, strong walls and good infill give the best results. I’ve been printing these in PLA with the following general settings:

The trays and rails print reliably without fiddly supports, which makes batch printing them for a larger system quick and predictable.
