This model is a single 40' shipping container, which has now been successfuly printed and so should no longer be showing as 'first to try'.
I also have 20' and 30' containers avaialble, and each of these sizes are also available in a set of 6 to reduce the unit cost.
I also have future plans for a container wagon with 3x20' containers (currently designed and ready for me to test print as part of my next order), or 1x20' + 2x40', and also road trailers with containers (printed as one piece - the trailers would be too delicate otherwise).
