Parametric Stackable Storage Tray

OpenSCAD tray with a built-in stacking foot. Set your Gridfinity footprint, partitions, and textures, then print as many as you need. I noticed that if I could stack the grids for small hardware I could save space.

How stacking works

Each tray has a foot skirt: a hollow ring below the tray body that drops into the inner cavity of the tray below. The floor slab underside of the upper tray rests on the top rim of the lower tray when seated. A 2° draft taper on the foot outer face and a self-centering chamfer on the bottom edge keep nesting snag-free.

Footprint is set by gf_cells_x × gf_cells_y (each cell = 42mm). The Gridfinity base is optional, toggled per tray. When on, GF socket cavities are cut into the bottom face of the foot skirt; when off, the foot is a plain hollow ring.

Features

Stacking foot with Gridfinity option The foot skirt fits inside the tray below with a gap controlled by stack_tolerance. Set gf_base = true and the foot bottom becomes a Gridfinity socket: the tray stacks on other trays and sits on any Gridfinity baseplate.

Gridfinity version needs support for printing, while flat baseplate version do not.

Partitioning Set column widths with col_widths (Golden Ratio default: [1, 1.618, 1]) and define row subdivisions per column independently via col_rows.

Sine Wave Fins Set any column in col_fins to true to replace row dividers with corrugated wave fins. Useful for screws, bits, or small parts. Control amplitude, period, count, height, and z-offset.

External Ribbing Optional vertical ribs on the outer walls. Adjustable width, depth, gap, and taper ratio.
