Let's create some duplo compatible train necessities:
- Tank wagon tops
- Nuclear waste containers (optional dual color print)
- Sea containers
- Roofs (for containers, crates or for train platform)
- Pillars (either for train platform or track transport)
- End of rail unit
- ... and more to follow ...
Some parts could be combined with one of these nice wagons: wagon1 or wagon2 and ofc you need a locomotive!
All provided STL's are generated with the duplo_specials_xy.scad and needs the "duplo interface" module. Also check these generators: tracks, crossings, funnels and flex tracks.
