Jet Engine — Assembled Cutaway Display & Source Kit

OVERVIEW
Jet Engine is supplied as a digital source kit for an educational engine-model subject. The replacement cover presents the model assembled as a finished cutaway display, based on an image included in the same source collection. It replaces the earlier board of scattered representative parts. The open casing sector intentionally exposes the internal stages; it is not an instruction to add a missing outer shell. The cover does not certify a recovered assembled 3D scene, a physically tested print, an exact bill of materials or a functioning turbine.

ASSEMBLED DISPLAY AND FINISH
The cover follows the supplied reference arrangement of the existing inlet fan, central spinner, visible compressor and turbine stages, shaft and casing regions, rear outlet and display support. The cover retains the orange-case and dark-fan display finish shown in the supplied reference. Paint and metal appearance are illustrative surface finishes, not measured alloy, temperature, strength or manufacturing specifications. Cutaway openings and any supplied stand are retained from the reference rather than invented as extra downloadable resources.

DOWNLOAD CONTENTS
The ZIP preserves all supplied STL variants, the OBJ viewing copy and the editable STEP assembly, together with 129 technical and reference images. STEP geometry, assembly references, units and colour definitions are retained. An English component inventory replaces a cropped, incomplete table and uses the current file identifiers; unverified quantities remain explicitly unverified. Keep alternate cutaway, support and size variants separate when planning a build. The completed-display image illustrates the assembly.

PRINTING ADVICE — UNTESTED
Inspect each chosen component in a slicer before printing. Confirm units, intended size, thin walls, open edges, intersecting shells, blade thickness, shaft clearances, casing alignment and support access. Fan blades, narrow stator vanes, concentric rings, small pins and cutaway edges can become fragile when reduced in scale. Plan supports so they can be removed without destroying adjacent detail. Material, nozzle, layer height or resin exposure should match the actual printer and dimensions; no tested preset is certified here. Print a representative blade, ring or joint sample before a full set. Keep repairs, splitting, hollowing and scale changes on copies. Any intended movement or fit must be checked against the source documentation and actual selected parts.

DIMENSIONS AND SCALE
Physical units, overall assembled dimensions and a specific miniature scale have not been independently verified by this correction. A board-layout bounding box does not establish assembled engine length or diameter. Confirm dimensions in the retained CAD or source documentation and your slicer. Calculate a resize percentage as target dimension divided by current dimension multiplied by 100. For a documented original 1:N scale and target 1:T, use N divided by T multiplied by 100. Recheck blade thickness, ring concentricity, joints, shaft clearance and stand stability after resizing. No flight, thermal, pressure or powered-operation performance is represented by this display image.

Untested source geometry. Confirm units, thin features, source documentation and clearances. No physical print, fit or mechanical function is certified.

Prepared for display and download. No physical print has been certified.
