I'm been doing some steam loco bodies in British OO9 scale (4mm scale 9mm gauge) I've just printed out my first batch of 5 in FD of which 4 came out really well but the 5th is a mess.

But the 5 th has a rough crystalline feel to one side where it should be flat

It is twisted front to back but about 5 degrees

Its sprayed outwards in the middle by about 2mm

and it has ridges across the back

So why did this one go so wrong when the other parts of the print worked fine ?
