A hobbyist has designed an HO double-stack well car: https://www.thingiverse.com/thing:426812 Two primary parts come together via clips before being securely fastened with glue or a weld. Precision is crucial when attaching detailed parts - opt for gluing or welding these to ensure they are firmly attached. Care must be taken when sizing holes for trucks and couplers, ensuring they accommodate 6-32 tap without issue. A washer or pocket/truck washer between the truck and body helps maintain structural integrity. This well car is designed to run on standard HO track, eliminating any potential issues with compatibility. Before use, remove excess material from the ends of the vehicle - this extra matter only exists for the purpose of making it easier to print. It's possible that the design might be slightly too small for certain containers. To compensate, you may need to enlarge it by one percent or slightly more to achieve a comfortable fit.
