schema_version: 1 name: aleph-stack-case intent: create a case enclosure for a full aleph stack, allowing for the heat sink to extend outside the top to allow airflow, and making sure to have openings for the J4, J5, J7, UARTs, the molex power port, eth gadget USB-C, and RPI debugger USB-C ports. This will be 3D printing in PETG, so make sure it has enough thickness for strength. Make sure the stack secures to the case via the top standoff screw holes. units: length: mm angle: deg material: PETG process: FDM / FFF 3D printing; two fixed printed bodies in one PartContract release_status: prototype frame: origin: 'Use the aleph-stack assembly origin: the intersection of the unrounded minimum-x and minimum-y base-board outline edges on the base PCB bottom plane z=0.

The 2.4 mm acceptance minimum is a prototype gauge, not a load or temperature rating; shop settings remain open. edit_test: delta: 0.8 expect: volume_delta: 8508.61408 direction: increase bbox_delta: [1.6, 1.6, 0.0] tolerance_rel: 0.3 sweep: values: [2.8, 3.2, 4.0] infeasible_deltas: [-3.2] - name: roofThickness value: 3.2 unit: mm provenance: inferred tolerance: 0.6 description: Roof gauge, independent of the side-wall edit. rationale: The roof carries the four mounting screw heads and spans the cavity; use the same structural nominal gauge as the walls until the shop confirms it. - name: floorThickness value: 3.2 unit: mm provenance: inferred tolerance: 0.6 description: Bottom-cover slab gauge. rationale: The closed bottom and integral compression pads need a structural PETG floor; use 3.2 mm nominal with a 2.4 mm verified minimum. - name: boardClearance value: 2.0 unit: mm provenance: inferred tolerance: 0.5 description: Offset of internal side-wall planes from the full stack x/y envelope. rationale: A small 2 mm allowance accommodates the source 0.3 mm envelope uncertainty and FDM fit without using connector anchors as connector outlines. A gap probe would have only 1 mm nominal margin, so clearance checks and planes are used instead. - name: floorClearance value: 1.5 unit: mm provenance: inferred tolerance: 0.5 description: Floor-to-lowest-modelled-component gap. rationale: Reserve 1.5 mm below the -1.97 mm component envelope; corner support pads are the only intentional contact with the base PCB. - name: seamGap value: 0.3 unit: mm provenance: inferred tolerance: 0.15 description: Vertical separation of the cap rim and bottom-cover slab. rationale: Two independently fastened fixed pieces need a small non-interfering seam. They register on the same stack axes; no sliding, hinge, snap-fit or kinematic joint is introduced. - name: roofSpacerHeight value: 14.0 unit: mm provenance: inferred tolerance: 0.5 description: Four proposed metal compression-spacer lengths above the carrier. rationale: A 14 mm spacer puts the roof underside at z 27.13, above the full z 25.97 module component keep-out, while keeping the fan outside. This avoids thin plastic lugs beside the rear SO-DIMM housing. Purchased or cut-to-length spacers must be confirmed. - name: roofSpacerDiameter value: 4.5 unit: mm provenance: inferred tolerance: 0.4 description: Proposed metal spacer outside diameter; spacers are hardware, not printed solids. rationale: A narrow 4.5 mm OD tube fits the corner axes, nominally 0.70 mm from the SO-DIMM x boundary at the rear. No commercial part number or thread engagement is assumed. - name: mountHoleDiameter value: 3.0 unit: mm provenance: inferred tolerance: 0.2 description: Case clearance holes for the eight M2.5 screws; top four are the required stack attachment. rationale: Use a provisional printed 3.0 mm clearance hole, slightly larger than the source board D2.9 holes. Verify the actual printed fit; the case does not contain printed M2.5 threads. - name: basePadDiameter value: 8.0 unit: mm provenance: inferred tolerance: 0.75 description: Four integral bottom-cover compression-pad diameters. rationale: An 8 mm pad around a 3 mm bore leaves a nominal 2.5 mm radial PETG ligament and transfers load to the base mounting lands. Availability of this larger underside land is an explicit open question. - name: portMargin value: 1.5 unit: mm provenance: inferred tolerance: 0.5 description: Tangential and vertical expansion of connector-body projections at service windows. rationale: Use 1.5 mm around supplied body envelopes as a provisional mating-plug allowance. Merge adjacent windows to avoid thin webs; cable overmoulds, latches and reach are not dimensioned. - name: heatsinkMargin value: 4.0 unit: mm provenance: inferred tolerance: 1.0 description: Per-side roof-opening allowance around the nominal heatsink footprint. rationale: A 4 mm nominal gap covers half of the +/-2 mm size uncertainty plus an inferred 0.5 mm centering allowance, leaving 2.5 mm to the conservative x/y keep-out. It also leaves substantial air access around the fan shroud. edit_test: delta: 0.5 expect: volume_delta: -377.6 direction: decrease bbox_delta: [0.0, 0.0, 0.0] tolerance_rel: 0.03 sweep: values: [3.5, 4.0, 4.5] infeasible_deltas: [-4.0] - name: innerXMin value: -2.0 unit: mm provenance: derived tolerance: 0.1 description: Internal -x wall plane. formula: stackMinX - boardClearance - name: innerXMax value: 91.31 unit: mm provenance: derived tolerance: 0.1 description: Internal +x wall plane. formula: stackMaxX + boardClearance - name: innerYMin value: -4.5 unit: mm provenance: derived tolerance: 0.1 description: Internal -y wall plane. formula: stackMinY - boardClearance - name: innerYMax value: 54.5 unit: mm provenance: derived tolerance: 0.1 description: Internal +y wall plane. formula: boardWidth + boardClearance - name: outerXMin value: -5.2 unit: mm provenance: derived tolerance: 0.1 description: Case minimum x. formula: innerXMin - wallThickness - name: outerXMax value: 94.51 unit: mm provenance: derived tolerance: 0.1 description: Case maximum x. formula: innerXMax + wallThickness - name: outerYMin value: -7.7 unit: mm provenance: derived tolerance: 0.1 description: Case minimum y. formula: innerYMin - wallThickness - name: outerYMax value: 57.7 unit: mm provenance: derived tolerance: 0.1 description: Case maximum y. formula: innerYMax + wallThickness - name: floorTop value: -3.47 unit: mm provenance: derived tolerance: 0.1 description: Upper surface of the bottom-cover slab. formula: stackMinZ - floorClearance - name: floorBottom value: -6.67 unit: mm provenance: derived tolerance: 0.1 description: Lowest printed face. formula: floorTop - floorThickness - name: shellBottom value: -3.17 unit: mm provenance: derived tolerance: 0.1 description: Lower rim of the upper cap. formula: floorTop + seamGap - name: roofBottom value: 27.13 unit: mm provenance: derived tolerance: 0.1 description: Roof underside, seated on the four metal spacers. formula: carrierTop + roofSpacerHeight - name: roofTop value: 30.33 unit: mm provenance: derived tolerance: 0.1 description: Top of printed case; below the heatsink top. formula: roofBottom + roofThickness - name: heatOpeningLength value: 69.0 unit: mm provenance: derived tolerance: 0.1 description: Rectangular roof opening along x. formula: heatsinkLength + 2 * heatsinkMargin - name: heatOpeningWidth value: 48.0 unit: mm provenance: derived tolerance: 0.1 description: Rectangular roof opening along y. formula: heatsinkWidth + 2 * heatsinkMargin - name: heatOpeningXMin value: 9.5 unit: mm provenance: derived tolerance: 0.1 description: Left roof aperture edge. formula: heatsinkCenterX - heatOpeningLength / 2 - name: heatOpeningXMax value: 78.5 unit: mm provenance: derived tolerance: 0.1 description: Right roof aperture edge. formula: heatsinkCenterX + heatOpeningLength / 2 - name: heatOpeningYMin value: -2.81 unit: mm provenance: derived tolerance: 0.1 description: Front roof aperture edge. formula: heatsinkCenterY - heatOpeningWidth / 2 - name: heatOpeningYMax value: 45.19 unit: mm provenance: derived tolerance: 0.1 description: Rear roof aperture edge. formula: heatsinkCenterY + heatOpeningWidth / 2 - name: caseLength value: 99.71 unit: mm provenance: derived tolerance: 0.1 description: Overall printed x span. formula: outerXMax - outerXMin - name: caseWidth value: 65.4 unit: mm provenance: derived tolerance: 0.1 description: Overall printed y span. formula: outerYMax - outerYMin - name: caseHeight value: 37.0 unit: mm provenance: derived tolerance: 0.1 description: Overall printed z span. formula: roofTop - floorBottom - name: fanExposure value: 8.19 unit: mm provenance: derived tolerance: 3.0 description: Nominal exposed heatsink height; 5.19 mm at the -3 mm height uncertainty. formula: heatsinkTop - roofTop features: - id: upperCap kind: shell description: One connected inverted rectangular cap.
