The problem

Rain gets in. Mail sits on the wet floor.

Wet letters

Outdoor letterboxes can collect moisture after rain, sprinklers, humidity, or a small leak around the door.

Rusty base

Older metal boxes often have uneven, stained, or rusty floors that hold damp patches longer than expected.

No perfect size

Most letterboxes are slightly different. A custom insert fits better than a generic tray or improvised mat.

Simple process

Measure, print, install.

Measure inside

Measure the internal length and width of your letterbox floor in millimetres. Add the front opening height if it is tight.

Upload a photo

A quick photo helps us check the shape, lip, door clearance, and whether a notch or split-piece design is needed.

Fit and forget

Drop the liner into the base. The raised grid helps lift mail above damp spots while gaps allow air to move underneath.

Designed for real letterboxes

A practical 3D printed insert, not a leak repair.

DryBox Liner is made to reduce contact between mail and damp surfaces. It is ideal for boxes that get mild moisture, pooling on the floor, condensation, or water blown in during rain.

If your letterbox has a major leak, damaged door, or standing water, the liner can still help raise mail, but the box should also be repaired or replaced.

Good to know

FAQ

Will it stop my letterbox leaking?

No. It is not a seal or repair kit. It helps keep mail raised above damp surfaces and improves airflow inside the letterbox.

What if my measurements are wrong?

We recommend uploading a photo before printing. For tight or unusual boxes, we can confirm dimensions before production.

Can I return a custom liner?

Custom-made items are usually not change-of-mind returns. If the item is faulty, not as described, or does not meet an agreed requirement, Australian Consumer Law rights still apply.

How long does it take?

Most orders can be printed and dispatched within 3-5 business days after measurements and photos are confirmed.
