I have printed out the first hopper of a new rake of about 10 that I am going to create. the cost of the plastic of each wagon is less than £1 so there should be a huge saving over the Bachmann model, although they take about 15 hours to print each, and ive already had to redo the bogeys so you pay in time. I'm thinking of painting them red, though I might do a couple in other colours, I still havent decided.
