This is a replaceable top for the motorized train chassis of the Duplo Sets 10874 or 10875.
No MMU / AMS required, just some screws (Spax 3x16mm), colored filament and glue.
(the face needs to be painted if you want to)
How to build it:
- print all the parts in the color of your liking
- glue in the windows, numbers, coal, roof and inserts in the base
- glue in the smokebox-rings in the smokebox
- screw in the base to the undercarriage (from the underside of it)
- slide the smokebox and chimney into the base and screw it on
- optional: paint the face
- glue the face onto the chimney faceplate
- glue the light onto the undercarriage
Done :)
