A complete starter set of Gridfinity-compatible storage bins: five footprints in two heights, every bin also with magnet pockets, plus two baseplates. Everything is generated procedurally to the published Gridfinity dimensions and verified watertight.

What's included (22 models, STL + 3MF)

• Bins: 1×1, 1×2, 2×2, 2×3, 3×3; each at 3u (24.9 mm) and 6u (45.9 mm) with a stacking lip
• Magnet variants of every bin: Ø6.5 × 2.4 mm pockets for 6 × 2 mm magnets (4 per cell)
• Baseplates: 3×3 (126 mm) and 4×4 (168 mm) open-bottom frames

Compatibility

42 mm grid, 7 mm height units, 0.25 mm clearance (bin = 42n − 0.5 mm), standard 0.8/1.8/2.15 mm foot profile and 0.7/1.8/2.15 mm baseplate profile; they mix with other Gridfinity-compatible bins and baseplates. Exact numbers are listed below and in the README.

Print settings

• PLA or PETG, 0.2 mm layers, 2–3 walls, 10–15 % infill, no supports
• Magnet bins: pause at ~2.6 mm to insert magnets, or glue them in afterwards

Gridfinity numbers used

GRIDFINITY NUMBERS USED (mm)
  Grid pitch 42 / height unit 7 / clearance 0.25 per side -> bin outer = 42n - 0.5 (41.5 per unit)
  Bin outer corner radius 3.75 (7.5 dia); baseplate cell & outer corner radius 4.0 (8 dia)
  Bin foot profile (bottom->top): 0.8 x 45deg chamfer, 1.8 vertical, 2.15 x 45deg chamfer = 4.75 tall, 2.95 inset
     -> foot bottom 35.6 mm square, R0.8
  Baseplate pocket profile (bottom->top): 0.7 x 45deg, 1.8 vertical, 2.15 x 45deg = 4.65 tall
     -> printed plate truncated to 4.45 mm (0.4 mm flat ridges instead of knife edges; all clearances unchanged)
     -> open-bottom 'lite' frame: 126 x 126 mm (3x3), 168 x 168 mm (4x4)
  Bin wall 0.95; solid floor top at z = 7.0
  Bin height: 7 x u to the top of the wall + stacking lip: 3u = 21 + 3.9 = 24.9, 6u = 42 + 3.9 = 45.9
  Stacking lip profile (from wall top, offsets from the outer face): 2.6 -> 0.7 x 45deg -> 1.9 -> 1.8 vertical -> 45deg to a 0.5 mm flat top
     (standard 0.7/1.8/1.9 lip, top truncated to a 0.5 mm flat for printability), 45deg support taper under the lip
  Magnet pockets (*_magnets files): 6.5 dia x 2.4 deep for 6 x 2 mm magnets, 4 per grid cell at +/-13 mm (26 mm spacing)

Blender check (live Blender 5.2.1)

• All 22 files: 0 non-manifold edges, 0 open edges, 1 shell, consistent outward normals, 0 degenerate faces.
• Stacking: a 1×1×6u bin seats on a 1×1×3u bin at z = 20.7 mm with 0 intersecting triangles.
• Baseplate: 2×2 and 1×1 bins drop into the 4×4 pockets with 0 intersecting triangles (bin bottom flush with the plate underside).
• One sliver triangle left by a boolean in the 2×3×6u bin was dissolved and the file re-verified.
• Not yet physically test-printed.
