A small box with lid that you can slide in and out, lid is fastend by small bulp on underside.

Please turn the lid upside down when printing, to lay it flat on the bed, the small bulb on the underside is easy to miss.  Otherwise just use the slice file

I printed the box in petg with 0.18 elephant foot compensation, which fits my printer and provides snug fit of the lid.

The box lid fastering is inspired by another design https://www.printables.com/model/962152-seed-box-gridfinity
