Two things go wrong with stackable storage, and both are manufacturing artefacts rather than design failures. Understanding them makes it obvious what to look for.

Why moulded bins lean

Any injection-moulded part has to come out of a mould, which means every vertical wall is slightly tapered — a draft angle, usually one or two degrees. Without it the part grips the tool and will not release.

That taper is invisible on a single bin. Stack three and it compounds: each one sits slightly proud on the taper of the one below, the contact is on a sloped surface rather than a flat one, and the column leans. Add weight and it leans further.

A printed bin has no draft angle, because there is no mould to come out of. It can have a genuine positive locating rim — a step that drops into the one below and locates it — so a column stays vertical whatever you put in it. Our stackable boxes and scalable storage bins are built that way.

Why the size is always wrong

Storage bins are sold in the sizes a factory finds efficient. Shelves are built in the sizes a room happens to be. There is no reason those should coincide, and they mostly do not — which is why there is always an inch or two of wasted space at one end of every shelf in the house.

Over a whole cupboard that adds up to a real fraction of the storage you are paying for.

Made to order changes this. Send the internal measurement of the shelf and the bins are printed to it. Most people ask for a run of three or four across, which uses the full width with nothing left over. It is a small thing that you notice every time you open the cupboard.

The cut-down front

A bin with four full-height walls has to come off the shelf to be used, and once it has to come off the shelf, the one above it has to come off first.

A front wall cut lower than the sides lets you see and reach the contents in place. That single feature is the difference between a stack you use and a stack you unstack.

Where rigid is wrong

A rigid box either fits what you are putting in it or it does not, and the moment you force it, a corner cracks.

A basket with a flexible woven wall gives instead. Our flex basket has walls printed as a lattice that takes a little more than its nominal volume without splitting and springs back when emptied — with rigid rims so several still stack squarely despite the flex in between.

That is a genuinely printing-specific solution: the flexibility comes from the lattice geometry, not from a softer material.

Colour-coding, which costs nothing

At print time, colour is free. Which means colour-coding by contents is not a luxury.

The value is at a distance — you identify the right bin from across a garage or a craft room without reading a label. Four colours is about the limit of what people reliably distinguish at a glance; beyond that you are back to reading.

A practical scheme: one colour per category, and a single contrasting colour reserved for “things to deal with”. The last one does more than the others.

Lids, and the hinge question

A loose lid is a lid you will lose. If the contents need covering, a printed hinge built into the body is better than a separate lid, because there is nothing to misplace and nothing to work loose. Our hinged storage box is printed as one piece — lid, hinge and body — with an overlapping lid that keeps dust out.

If the contents do not need covering, skip the lid entirely. Open bins get used; lidded bins get stacked and forgotten.

Loading a stack sensibly

  • Heaviest at the bottom. Obvious, and constantly ignored.
  • Most-used at the top, so you are not unstacking daily.
  • Do not exceed three or four high for anything you access regularly, whatever the bin can structurally take — the limit is your patience, not the plastic.
  • Leave a couple of centimetres of headroom above the top bin, or you cannot get it out.

The measurement to send us

Internal width between the shelf sides, internal depth from the back to the front edge, and shelf-to-shelf height. Three numbers, one minute with a tape measure, and the storage fits the space instead of nearly fitting it.

The storage and organisation range is printed to order in Canada.
