A compact, highly detailed model of a traction-style portable steam boiler from the Edwardian era — perfect for HO model railways, industrial dioramas, and display cabinets. This purchase provides a single 1:87 (HO) master STL plus an orthographic 6-view PDF with datum annotations to help with layout placement and conversion. The geometry includes the main boiler shell with chimney, four-spoke wheels, seat pan, drive pulley, rectangular inspection door and a row of service ports. Print recommendations: FDM at 0.12–0.18 mm layers with supports under chimney and seat; resin printing at 50–75 microns for maximum detail. The model is ideal as a trackside prop, yard stationary boiler or workshop accent. Note: only the 1:87 master STL is included; conversion guidance is provided in the PDF.
Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
