Three stackable desk drawers, 60, 90 and 130 mm tall, in a tower 200 × 240 mm and 280 mm tall, the shallowest on top.

Three drawers and nothing on top: the shallowest, 60 mm, at the top for pens and cards, a 90 mm drawer for stationery under it, and a 130 mm drawer for chargers and tape at the bottom.

Each drawer has the grip that suits its height: a notch on the shallow one, a slot on the middle one, and a lip to hook under on the deep one. The top shell is flat, so it can take a monitor stand or a lamp.

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.
