Built inside a working warehouse.

We've been running our e-commerce store — DIY Wrap Club — for the past seven years. In that time we've tried just about everything: expensive Uline bins, big industrial racks, smaller racks, mix-and-match systems. Anyone who's done this has the same story.

The thing you eventually learn: you don't have to reinvent the wheel. Watch what the big players do and copy it — or at least mimic it.

We already had a stack of 48×72×24 wire shelves — the cheap kind you can grab at Home Depot under names like Project Source or Muscle Rack. Over the years we'd collected three different brands of them, and that was the catch: every divider system on the market only fit one brand.

We didn't want a new rack. We wanted a divider that worked on the racks we already owned.

Amazon uses a dynamic shelf-dividing system with an elastic strap across the front, so product doesn't fall out the top or the front, and the dividers slide as demand shifts. You can't buy it anywhere. So we designed our own in CAD.

Simple thumb-screw mechanism. A slot that accepts any 32-ECT cardboard panel. Compatible with 2×1 labels. Works on every generic wire rack we owned.

Our shelves run a simple grid: shelf 1 has bins A, B, C, D, E, F, G; shelf 2 has the same; and so on. The dividers support that labeling out of the box (and any other system you want to run).

We saved a lot of space. Our inventory got more dynamic, which saved money. Our fulfillment team built a clean wave-picking flow on top of it. And because everything is modular, we just add more as we grow.

We have the 3D printers and the machinery already running. This isn't our core company — but other warehouse operators kept asking, and it helps subsidize our printing costs. So if you want a kit, we'll print it and ship it.

Next up: a top-of-shelf bracket so you can label whole zones cleanly — "shelves 1–5" here, "6–10" there. It's almost done. More to come.
