RC controlled shunting locomotive in zero gauge 7mm scale Free 3D print model

Hans Gerstenkorn – German Engineering presents a 1:43 scale, also known as 7mm scale, model of a generic shunting engine. The model is meant to be remote controlled and battery powered. All chassis and body parts are designed to be 3D-printed, preferably with a resin printer. These locomotives have been built since the 1920 by various companies. They are electric powered with batteries, hence no pantograph and catenary wire is needed. The have been used locally for industrial and works railways. This model locomotive represents a generic standard gauge accumulator locomotive used for shunting. The model conforms to the MOROP NEM (Home - MOROP) norms NEM 110 (32mm gauge), NEM 301 (boundaries), NEM 303 (buffer), NEM 310 (Wheel gauges), NEM 311 (wheel profile for 32 mm gauge) and NEM 362 (coupler mount) and shall therefore be usable on all commercially available Zero Gauge / 7 mm model track systems. Included 3D printable Models: • lower chassis • motor mount for N20 geared motor • upper chassis • side beams • wheel • Body • headstock with buffers and hook • track sweeper • coupler mount • tank • wheel brake model • ladder • handrails • horn • bevel gears
