US Bobber Caboose Scale 1:32 - OpenRailway

thingiverse

This is a scale 1/32 model of a Bobber Caboose for a garden railway that runs on 45mm tracks. Cabooses are manned North American railroad cars coupled at the end of a freight train. Early cabooses were named "Way cars." This model, with a cupola, began its service in the late 1890s. The two-axle Bobber caboose was known for its uneven ride due to the lack of trucks it created. The model uses three-millimeter wheel axles and a LGB-like coupler holder so it can accept either LGB standard couplers or knuckle couplers. Print Settings: Printer: Vertex 8400 Rafts: No Supports: Yes Resolution: 0.1mm or 0.2mm Infill: 40% Notes: I've printed everything in ABS, which is easier to sand/file and glue. The stairs need support and must be printed with a 0.3mm wall thickness. The cupola is a bit tricky to print due to big overhangs, so you may want to use a file with support or without it depending on your printer. All the small pieces are printed with a 0.1mm layer thickness, while the bigger ones have a 0.2mm layer thickness. The roofs are printed vertically and come with an easily removable brim; I've included a version of the bigger one without a brim for those who can't print it vertically. Post-Printing: Bobber cabooses were usually painted brownish red but also came in bright red or yellow. This model existed with or without a central window on the cupola, and both versions are available in the STL files. First, assemble the wheels, outer axles, and axles; use metal shafts three millimeters in diameter if you want your model to roll smoothly. Insert the axle holders into the slots at the bottom of the cabin by tilting them outwards; this will allow you to attach the wheels assembly next. Screw the toolbox to the bottom of the cabin with a two-by-ten (or two-by-twelve) millimeter screw when everything is in place. Glue the four brakes in their corresponding holes and screw the coupler holders into place using two point-five-millimeter screws on each side. Glue all the windows in the cabin and cupola, making sure to add clear plastic sheets on the inner side of the windows first. Cover the chimney hole with a scrap of ABS on the inner side of the roof. Insert the beam holding the roof and cupola with the notched ends upwards; this will help you attach everything securely. Screw the cupola to the beam through the roof using two point-five-millimeter screws, then use a two-millimeter screw to hold the roof in place on the other side. Screw the cupola roof into place with two millimeter screws and glue the chimney (which you should have glued together first) into its hole. Glue the front and rear gangways into their corresponding holes; feel free to bend the rear gangway and lateral part of the front gangway to follow the curve of the roof. Glue the handrails to the lateral and front sides of the cabin, then glue the platforms (the one with a brake wheel hole is on the side opposite to the cupola). Insert the big guardrail into the ladder, making one of the rungs, and glue it into the corresponding holes of the platforms. Adjust the ladder so its upper part rests against the roof. Glue the two handles on the front side of the platforms, then glue the brake wheel into the remaining hole of the front platform. Finally, glue the handrails on the cupola roof and the handles on the gangways to complete your caboose.
