Train Cars

thingiverse

Flatbed train cars designed for popular 1" gauge wooden tracks and compatible with other types of tracks. These cars have magnet pockets on the ends to hold 6.5mm N42 magnets that fit perfectly into place. The wheels serve as creative Lego mini-fig hats, adding a playful touch to any model train setup. The provided files do not include letters or other written content. Print Settings: Printer: FlashForge Dreamer Rafts: No rafts are used in this printing process. Supports: Supports are not needed for these prints. Resolution: The prints have a resolution of 0.18mm, ensuring high-quality details. Infill: A moderate infill percentage of 15% is used to achieve the right balance between strength and detail. Notes: I'm printing these train cars out of ABS plastic, which may affect tolerance due to variations in PLA materials. If you decide to switch to smaller metal axles, study the hub pattern on commercial wheels for optimal results. Inserting magnets and assembling wheels onto axles becomes easier when parts are still warm from the printer. To simplify the printing process, I'm printing these cars in three parts: all four wheels first, then the carriage, and finally a pair of axles with a raft. Post-Printing Assembly: Press 6.5mm magnet cubes into their designated pockets, making sure to achieve the correct polarity. Snap fit the wheels onto the axle/carriage, and your flatbed train car is ready for use. Attach your preferred topper and enjoy playing. How I Designed This: OpenSCAD I used basic hull functions to create filleted wheels, which took some time to render but resulted in a smooth design. Initially, I considered using acetone to bond the wheels to the axles, but they ended up snapping together securely without any adhesive. You can still choose to use bonding agents if you prefer.
