REVISION H PROTOTYPE - ORCASLICER BRIDGE CORRECTION

Verified with OrcaSlicer 2.4.2, P1S 0.4 mm, ASA, 0.20 mm layers,
6 walls / 6 top and bottom / 100% rectilinear / 8 mm outer brim / supports off.

For both ducts (03 and 04), keep the supplied inlet-down orientation.
Set Bridge direction to 180 degrees (Orca uses 0 for automatic).
Set Internal bridge direction to 180 degrees too. Turn OFF Relative bridge
angle and Align infill direction to model. In this baked orientation the
bridge lines must cross the narrow dovetail slots, along plate X.

At Z=2.2 mm inspect the long slots near the plate sides. Automatic direction
creates unsupported lengthwise paths around 124 mm. The corrected slices
have maximum unsupported spans of 5.19 mm and zero disconnected floating
components in the deposited-path screen. A slicer floating-region warning
may still appear: inspect the actual paths, especially the first slot roof.

Reviewed estimated totals: left duct 132.96 g / 3h 58m 55s;
right duct 132.98 g / 3h 55m 42s. These include the selected brim/settings.
These are geometric toolpath checks, not an ASA bridge or retention test.
Verify your actual filament temperatures and printer profile before printing.

The two .gcode.3mf files are Orca PREVIEW artifacts with embedded G-code,
not portable geometry-only models. Open for inspection; re-slice with your
actual spool settings. They have not been sent to a printer.

The STEP geometry is unchanged. All 14 parts remain the preserved Rev H
prototype; future ducted designs and Minimalist use their own revisions.
