Houseplant pot 120 mm in its 150 mm saucer — an everyday pair for small indoor plants, the pot on ribs above the water, 113.4 mm tall in all.

The Houseplant pot 120 mm standing in the Plant saucer 150 mm made for it: 120 mm across and 105 mm tall, in a saucer 30 mm wider, with 15 mm all round to catch what drains out.

Seven 6 mm drainage holes let water through, and six ribs hold the pot clear of it, so a pothos, a peperomia or an African violet can stand on a shelf or a table that water would mark.

Top to bottom. Every piece is the same width and depth, which is what lets them stack: tabs on top of each drawer drop into recesses under the piece above it.

Each version keeps its own size, file and license. An earlier version stays available if this one changes.
