Modular desk organizer

Build your desk, one 50 mm block at a time.

Pen cups, bins, a sticky-note tray, a phone stand and more, all on one 50 mm grid. A small printed dovetail key locks any module to any other. No tools, no glue, no hardware.

The clip system

One key. Every module. Any arrangement.

Every face of every module has a vertical dovetail groove at each 50 mm grid point. There is no male or female side, so any face can join any other face.

1

Set modules side by side

Everything sits on the same 50 mm grid, so grooves line up on their own. Modules leave a 0.5 mm gap between neighbours.

2

Drop in a bow-tie key

The key slides down into the two facing grooves and stops flush with the module bottoms. The joint resists pulling apart and sliding.

3

Lift to rearrange

Pull a module straight up to move it. The key stays in its neighbour. Add new modules whenever you like.

FAQ

What is it made of?

PLA plastic, printed to order. Choose a color at checkout: Black, White, Gray, Wood-look PLA or Navy blue.

Do I need tools or glue?

No. Drop a key between two modules and they lock together. Lift a module straight up to move it.

Can I add modules later?

Yes. Every module sits on the same 50 mm grid and works with every other module.

Will my phone fit the stand?

The universal stand fits most phones in cases up to 14 mm thick and about 150–175 mm tall, in portrait. Phones wider than the 91.5 mm back plate overhang it at the sides. Very thick rugged cases may not fit.

Is PLA OK in a hot car or a sunny window?

PLA softens at around 55–60 °C, so keep it out of hot cars and direct summer sun.

Every order is printed to order and ships in 3–5 business days. USPS Ground Advantage usually delivers 2–5 days after that, and we email your tracking number when it ships.
