This listing supplies a flat-shaded, unbranded full-size passenger sedan prepared as a single HO 1:87 master STL intended for hobby use. The design focuses on robustness and visual clarity at small scales rather than precise prototype detail. The model presents a simplified modern-sedan silhouette: broad faceted body panels with restrained crease lines, low-profile integrated bumpers, recessed wheel cavities, and blocked (solid) windows. Wheels, separate chassis or interior components are not provided.
Visible features and modelling choices
- Flat-shaded surfaces: broad planar faces reduce tiny overhangs and fragile micro-detail. The faceted look is intentional to simplify sanding, primer and weathering at HO scales while reading correctly from normal viewing distances within layouts.
- Integrated bumpers and smoothed transitions: front and rear bumpers are modeled as low-profile extensions of the body shell rather than thin appendages, reducing breakage during printing and handling. Door seams are suggested by shallow panel lines instead of open gaps to keep the mesh watertight and easy to slice.
- Recessed wheel geometry: wheels are represented by recessed wheel cavities sized to give a consistent footprint and strength. This single-shell approach omits separate wheel parts to improve durability; aftermarket wheel plugs can be fitted by the user if removable wheels are required.
- Blocked windows and simplified interior: windows are closed solids with no separate glazing or interior seats. This reduces print failure risk at small scales and produces a durable exterior prop suited for scenes where interior visibility is limited.
- Watertight single-shell body: the delivered file is a sealed, single-body shell with stable geometry suitable for reliable slicing across common hobby slicers.
What you receive
- One master STL prepared and scaled for HO 1:87 (1:87 master only). The file is intentionally a single watertight body with recessed wheel cavities and closed windows. No separate wheel parts, chassis or interior details are included.
Print notes and recommendations (HO 1:87 master)
- Orientation: For resin printers consider roof-down orientation (roof flat on the build plane) to minimize visible support marks on the most prominent surfaces. For FDM, orient upright or slightly tilted and enable multiple outer perimeters to improve edge strength.
- Supports: Minimal supports are recommended under recessed wheel wells and any undercut at the lower bumpers. Avoid heavy supports across large flat side panels to preserve the flat-shaded aesthetic.
- Layer height: For high-detail resin prints choose 0.05–0.10 mm layer height; FDM hobby prints typically balance speed and visibility at 0.12–0.16 mm.
- Structural advice: The single-shell, recessed-wheels approach trades separate details for robustness. If you require removable wheels or hollowed sections, modify the master in CAD or request a custom conversion.
Scaling guidance
- This product ships as a single HO 1:87 master STL. To print at another scale, uniformly scale the model in your slicer or CAD tool. Example multipliers relative to the 1:87 master: 1:76 (OO) — scale to 114.5%; 1:48 (O) — scale to 181.25%; 1:160 (N) — scale to 54.4%. Always verify minimum feature widths and run a print test after scaling. Only the HO 1:87 master is provided.
Intended uses
This simplified full-size sedan functions as a flexible passenger car prop for HO model railroads, modern dioramas, tabletop vignettes, street scenes and parking lots. Its single-shell construction and simplified underbody make it especially useful where durability is more important than intricate interior detail.
Limitations and notes
- Unbranded legacy origin: manufacturer badging, era-specific trim and exact prototype match are intentionally omitted. The decade and identity are inferred from the styling and are tentative.
- Missing features: no separate wheels, chassis or interior details are included. Those can be added by the user or via a custom commission if removable wheels or era-specific trim are required.
Customization
If you need removable wheels, hollowing, era-specific trim or alternate scale files, contact Miniature Reality for custom work. The current listing provides one HO 1:87 master STL optimized for reliable small-scale printing and robust tabletop presentation.
