There are several clips in the universes for the Ikea Samla boxes. My perferred one is the clip from Slaig: https://www.printables.com/model/367033-never-lost-ikea-samla-clip-remix-11l-22l-45l-65l

as it do not add much height.

These clips can also work with a seal on the box rim. I use these clips on my dryboxes:

Unfortunately, Ikea seems to have changed at least their 22l Samla boxes on the upper rim (edge) in 2025. Stiffeners have been moved from the long sides to the narrow sides. The very good “Never lost clips Remix” will not fit on the narrow sides in origin size anymore. Therefore I remixed the clip to a V2 version.

This clip will fit best on the Samla boxes 11l and 22l.

Please use the orgin clip for 45l and 65l (see link above). The snug fit in the upper rim will be better.

To be printed with at least PETG to avoid breaking. A brim is added to the profile.

Use some glue or double-sided tape for a durable fixation on the box edges.
