A simple clip to hold mini swatches at the top of cereal box dryboxes. These fit against the outside of the container, and should not extend beyond the top clips so don't take up extra space. They are fairly small and take about 4.6g and 4.1g total.
I've tested with PRAKI containers and Utopia Kitchens ones. Others might also fit since general aspects of the two container design seem to be sold under many brands.
They should print simply in the orientations presented, with the swatch areas parallel to the print bed. Tree supports might print slightly cleaner, but check for your setup.
Note that the clip for the front of containers is slightly curved on the bottom so supports will be needed and some bridging tuning might help.
