Having accidentally thrown away the drain pipe pieces for a Peco goods shed kit after forgetting to cut them from the sprue, I had to improvise.
I found some relatively straight looking twigs from the garden (not sure what kind of plant they were from). Covering them in poly cement allows them to be reshaped without them snapping until the glue dries, so I used this to straighten them by simply massaged them into shape easily. I don’t know what kind of twigs this will work for, but it worked really well with whatever I was using.
To make bends in the drain pipes I simply bent the straightened twig and covered the bent part in superglue to retain the shape.
Here are some photos showing the twigs before and after straightening, the unpainted and painted drain pipes, and the drain pipes on the final model.
