Stackable storage bins and baseplates in two grid standards: Gridfinity-compatible 42mm, and an original 50mm grid for larger parts.

What you get

1x1x3 bin and 2x2 baseplate in both gridsSeparate PLA (FDM) and resin (MSLA) versions — different wall thickness, fit clearance, and drain holes for resinStacking lip on every bin so they nestA fit calibration coupon: print it once, find the socket that fits your printer, and every part in the set matchesThe parametric source script — generate any bin size (1x1 to 6x6, any height) yourself

Specs

Gridfinity grid: 42.0mm pitch, 41.5mm footprint, 7mm height units, standard stacking profile50mm grid: 49.4mm footprint, 10mm height units, single-taper baseWalls: 1.2mm (PLA) / 1.6mm (resin). Floor same.All meshes watertight, verified manifold

Printing No supports needed. Resin version has 3.5mm drain holes in each foot — do not skip these, trapped resin ruins the cure. Print the coupon first.
