This printable G1 Phosphate Gondola model in HO 1:87 scale and N 1:160 scale just needs trucks and couplers/box. These are rotary dump gondolas that have been hauling phosphate in Central Florida since the 1970s by Seaboard Coast Line, Family Lines, Seaboard System, and CSX. The HO model consists of five STL files: the car body and four ladders (one piece models with ladders attached are also included). The N model comes in two forms, one with separate ladders and one with molded on ladders. Also included are HO and N Sketchup files. The Sketchup files are water tight, print ready, and can be edited and rescaled. Note that the scaling in the Sketchup files is ten times larger than the scale size due to Sketchup performing poorly at tiny scales. The HO scale body measures 134mm.
