What the geometry shows

Read from the v2 port graph. These are routes in the model. The 38 endpoint checks and bore checks do not measure flow, heat, or safety.

1. Clean feed: tank side bore, isolation/check provision, metering pump, flowmeter, then the heater channel. The whole clean run stays left of the waste tank.
2. Heated channel to an elevated nozzle at z480 mm. Maximum waterline is z420 mm. The 60 mm gap is open air. Beads show falling water, not a connecting pipe.
3. Salt cartridge and gate drop through a chute into the chamber annulus. The chute does not climb. Clean water upstream stays unsalted.
4. Recirculation is its own loop: a bar screen in the chamber, a bored wall port, a service union, a pump placeholder, and a return tee. It is not implied by a floating line.
5. Drain: open low point at z235 mm, normally closed valve (inlet z215 mm, outlet z185 mm), then a route that does not rise, into a receiving coupling at z135 mm and a stub at z120 mm. Waste max fill is drawn at z95 mm. The valve’s default gate is closed.
6. Basket, steam standpipe, and dry bay stay. The standpipe is on the rim, not on the lid. Steam leaves away from the dry bay. The raised basket clears the rim by 15 mm in the service view.

What the geometry checks cover

Each saved state rechecks 38 endpoints against the port collars, within 0.01 mm, plus bore-axis tangents. The drain centerline does not rise. The air gap is 60 mm. The raised basket clears the rim by 15 mm. The smallest nozzle or steam collar clearance to the basket sweep is 5.247 mm, with no tolerance stack. Distinct circuits stay apart in the sampled checks. These are not hydraulic, thermal, structural, or safety tests.

Open before any build

• Still unengineered. Food-contact materials, leak containment, dry-fire and flow protection, power arbitration, pressure and scale, condensate, an interlocked hot lift, drain temperature, overflow, and a full-waste stop. The closed valve and the max-fill line are drawings, not those controls.
• Backflow and overflow. Anti-siphon compliance is not designed. No emergency overflow pipe was added. A fail-closed feed, high-level detection, and a real containment path are still requirements.
• Starch and service. Screen spacing, pump compatibility, fouling, and the union removal sequence are untested. The heated channel is meant to see clean water only.
• Dry bay. Steam is aimed away from the bay. The barrier does not prove ingress, grounding, or a rated electrical compartment.

No bill of materials, wiring, or fabrication instructions. The checks do not certify the machine.

Generated locally with Blender’s Python and the built-in glTF exporter. Cycles CPU, 24 samples. No downloaded product meshes. Concept geometry, not a fabrication package.

Reproduce with Blender 4.2.9: blender -b -t 6 --python generate.py, then python3 presentation.py. Raw renders and the build log stayed with the generation record.
