I've recently had to change the lifting 'rings' to 'loops' to ensure the model prints without problems. Requested by a modeller, this is the N-scale version of the Titan Rocket shipping container and Air-Conditioning unit, for use on railroad flatcars. Modelled from photos, this is a fairly accurate model that would look good on a flat car. Each flatcar had two containers and two A/C units. For N-scale, please choose the FXD material to ensure the detail prints ok. If you are interested in several of this models please contact me, as it can often work out cheaper for me to create multiples for you to order rather than singles.
