This download includes the .STEP file for the Baldwin 0-6-6-0 DE diesel (an early version of the DR 6-4-2000) shell in HO scale. Two demonstrator units were built with this unique EMD-knock-off cab and were eventually sold to N de M. This is not so much a finished model ready for printing, but more of a starting point. You’ll likely want to add more details and mounting points for a mechanism before printing. As a result, I’ve included the .STEP file which should be easy to alter with most solid modelling software like Fusion 360 and Solidworks.
