River Trip A — HO 1:87 master STL River Trip A is a purpose-designed, short river/stream vignette sculpted to slot cleanly into HO (1:87) model railroad layouts and small dioramas. The top surface presents a recessed water plane sized for epoxy or clear gloss media, broad softened bank slopes for turf and small vegetation, and shallow rock clusters concentrated along the inner channel. A thin flat rim around the top edge lets you glue the piece flush to adjacent layout plate edges. The underside includes a keyed recess engineered to index the part to cork bedding, modular plates, or custom subplates so the top surface sits flush with surrounding scenery. What you get - One locked HO (1:87) master STL: River_Trip_A_1-87_master.stl - Readme.txt with recommended print orientation, support guidance, and a concise scaling/conversion blurb for other scales Printing notes Print flat with the top facing up so the keyed underside registers correctly. Recommended layer heights: 0.10–0.20 mm for FDM and 0.05–0.10 mm for resin. Most bank features are largely self-supporting; use minimal supports for isolated undercuts. After printing, the recessed water plane can be filled with epoxy or simulated water products to create convincing water effects. For final assembly glue the thin top rim to your layout plate using PVA or CA. Scaling and limitations This listing provides a single locked HO (1:87) master STL only. The included Readme contains scale factors for common modeling scales and advice on verifying keyed underside fit after scaling. Because this file originates from a legacy MeshRef stub, identity and dimension metadata are low confidence — we recommend a quick manual inspection of the STL after download.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
