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 — 240×205×87mm · 121g PLA · 3h 50m

▸ 𝟮𝟱𝟬𝗴 𝘀𝗵𝗲𝗹𝗳 — 168×144×61mm · 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, 220°C nozzle, 60°C 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.

Got a spool size or a storage setup this doesn't cover? Drop a comment and I'll see what I can do. And if this one earns a spot on your bench, a like, a favorite, or a boost genuinely helps — follow along for new designs and updates. Happy organizing! 🎯
