Filament Storage Shelf

The "Finally, a System That Actually Works" Modular Filament Rack

You know the drill. Vacuum bags sliding around in a bin, open spools stacked wherever they'll fit, and a five-minute excavation every time you need a specific material. I got tired of it. So I took the classic office paper tray, made it heavy-duty, and built it specifically around the 3D printing workflow.

WHAT MAKES IT WORK

Handles Everything — Vacuum sealed factory bags, home-resealed bags, and open spools all live comfortably in the same system. No more separate solutions for different storage states. Modular and Expandable — Stack as many shelves as your collection demands. Each unit is self-contained and the system grows with your filament library. No Supports Required — Redesigned geometry means no cleanup, no scarring, just clean prints off the bed. Under 125g Per Shelf — Efficient enough to batch print without burning through your filament stash building the organizer for your filament stash.

TWO SIZES INCLUDED

1000g shelf — 240x205x87mm, 121g PLA, 3h 50m 250g shelf — 168x144x61mm, 55g PLA, 1h 53m

Both live in the same 3MF as named plates — open it, pick "Standard - 1k spool" or "Smaller - 250k spool", and slice.

PRINT SETTINGS

No supports, 0.20mm layer height, 10% Gyroid infill, 2 walls, 150-300 speed, PLA

The 3MF is pre-configured and ready to slice: 0.4 nozzle, rear-aligned seam, 5 top layers, 3 bottom layers, outer wall 150 / inner wall 300 / infill 270, 3mm brim (outer and inner) with 0.5mm gap, 220C nozzle, 60C bed.

A full Print & Assembly Guide is attached under Instruction Files — both plates, the complete profile, and how to stack the rack.

THE REST OF THE FAMILY

Filament Storage Top Labels — a wide bar that caps a finished column and names the material in that stack. Separate model on my profile. Filament Storage Insert Labels — labels that sit inside a tray alongside the spool. Separate model on my profile. Filament Storage Side Labels — friction-fit tags for the side wall of each tray, readable even when the column is stacked high. Separate model on my profile.
