YOUR NUMBERS, YOUR FILES
Two separate STL solids, a dimensioned SVG, BOM, parameters,
assembly plan, and an unperformed inspection sheet.
STL is unitless. Import explicitly as millimetres. Review only, never a machine-ready claim.
Everything stays local. No accounts, uploads, or background requests.

|---|---|---|---|---|---|
| Stackline | 180 × 100 × 32 | 151.67 g | 6.00 min | $7.61 | ZIP ↓ |
| Compact | 140 × 90 × 28 | 103.67 g | 5.67 min | $6.23 | ZIP ↓ |
| Pocket Arcade | 180 × 100 × 28 | 140.96 g | 6.75 min | $7.60 | ZIP ↓ |
Compact: about 32% less nominal solid material than Stackline.
Pocket Arcade: an assumed 88 × 63 mm card footprint and 20 mm tokens. No actual game-piece fit test.
All dimensions use mm. Tray volume = outer width × depth × floor + wall-ring area × (height − floor). Insert volume = two full-width rails + the crossbars between them. Shared-volume overlap is removed before STL triangulation.
Mass (g) = solid volume (mm³) ÷ 1,000 × assumed density (1.24 g/cm³). Gross feedstock = mass ÷ 0.92. This is a solid geometry model, not a slicer/infill/support estimate. STL volumes are checked against those formulas.
Modeled bench effort = 300 fixed seconds + 20 seconds per bay + 45 seconds for a card/token review. It includes assembly, handling, and inspection, excludes fabrication/postprocessing, and is not time-study evidence.
Synthetic unit USD = gross feedstock kg × $24 + bench hours × $22 + $0.35 packaging + $1.10 overhead. Twenty-kit totals are rounded after aggregation; $7.61 × 20 is not the unrounded baseline batch result of $152.13. Density/price/yield sensitivity is in every review JSON.

The seed’s wider proposal needs 200 mm including two 2 mm pads. Its synthetic packing interior is only 192 mm.
No silent approval. Reopen geometry, fit limits, material, cost, and packaging review.
Inspect the change-impact record ↗TWO PARTS. NO HARDWARE.
After separately approved prototype, material and process reviews, a future pilot would follow this sequence.
Full prospective assembly instructions ↓Match pair and revision IDs. Record dimensions and edges. Never mix variants or invent readings.
Rails front/back, insert onto the floor. No fasteners, adhesive or forcing. Check all four gaps.
Review seating, retrieval and stability. Segregate binding or mismatched pairs for design review.
