Lego duplo wagon citerne

this is the "citerne" (tank) version of my lego duplo wagons series.
Wanted to have yellow bright color on them with shell logo, hadn't the right color.

This is just the tank part. You can put this piece on the top of a classic lego wagon (8x4 studs).
You will find them with my other wagons.
Needs to print 3 parts: 2 stands, which are at lego size, one tank.
I could print the tank vertical, no need for support.
When printing, you can choose the option not filled, only put 4 peripheral
