An N scale model of an H39B hopper. Originally built for the Pennsylvania railroad this model in particular is was modelled off one that reached usage with Conrail. Designed to work with microtrains trucks with Couplers attached. Part #1139 suggested.

One version is a full model that can be printed in one shot but I personally had warping issues doing so

Second Version is parted out to an A and B end with a keyed interface.

Rods across hopper are for support and can be removed post printing.
