Drawn with TinkerCAD. Based loosely on drawings on the MWB website. For more information on the construction process see - https://riksrailway.blogspot.com/2021/10/how-i-constructed-kerr-stuart-0-4-2t.html
The loco is designed to fit on the Bachmann Lyn motor block but could easily be modified to fit on any 0-4-0 motor block or chassis. The design varies from the original as I wanted it to run on 45mm gauge and hence it has been drawn in 15mm scale to represent three foot gauge track. The parts could be scaled up slightly (107%) in your slicer if you wanted a 16mm scale version.
Variants are provided for some of the parts which reflect changes made during the construction process. For more information on these see my blog post (link above)
