This HO 1:87 master STL is a compact travel trailer (camper) body with an attached raised porch, two short stair flights and diamond-pattern lattice skirting beneath. The model preserves three rectangular side window openings and a single entry door, plus horizontal siding with a mid-band detail that accepts masking and paint separation. The porch has vertical posts and evenly spaced balusters; the lattice skirting features consistent diamond cells sized for HO appearance. Included: one watertight STL scaled to HO 1:87. We supply only the 1:87 master file; use uniform scaling in your slicer for other ratios. Print notes: thin balusters and lattice are best in resin; FDM requires increased wall thickness and supports under deck and stairs. The mesh is designed with datum planes to ease seating on a layout base and to support splitting for removable roofs or chassis add-ons. Ideal for HO model-railroading layouts, camping dioramas, display scenes and tabletop props. No branding or interior detail is included; roof geometry is simplified due to source cropping.

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