LNWR

My Merlin!

 Mostly to 10mm scale.  Printed on an Elegoo Neptune 3 Pro, with PLA plus filament.  Two N-20 motors power the drivers, controlled from the tender by batteries and a small DC motor controller.  

This became the standard LNWR van from the mid Edwardian period up until grouping. They were used for traffic until the mid 50s at least, and some survived in departmental use for much longer. Note that it has been designed for resin printing on an Elegoo Saturn or similar. I don't know whether it can be printed on a filament printer (but let me know if you try!)
