Stackable Interlocking Bins

A modular storage system you can print yourself. The bins come in two sizes and they all clip together, no screws, no glue, no extra hardware. Print exactly the combination you need and snap them into a solid wall or shelf.
 

The sizes are based on paper formats. The A5 bin fits a sheet of A5 paper in its base, the A6 bin fits an A6 sheet. That makes the footprint easy to plan around, and it means you always know how much room a bin takes before you print it. Drop a labeled sheet in the bottom and you have an instant size reference or a quick way to mark what goes where.
 

The clever part is the connection. Every bin shares the same interface, whether it is small or large. You can mix sizes freely, stack them on top of each other and line them up side by side. When your storage needs change, you just rebuild.
 

I designed the whole thing with a clean industrial look. Hard edges, ventilation slots, visible structure. It looks right on a workbench, in a hobby room or in a stockroom, and not like just another plastic tray.

Good for Screws and small parts, electronics components, workshop gear, craft supplies, shipping material. The open front makes grabbing things easy, and stacking lets you make full use of your wall or shelf.

Tested with PLA, PETG and ASA, all snap together fine, PETG is naturally a bit more loose since it shrinks.
