Amazon Useful Items for Model Railways

I only recommend products I use or have used in the past.

I am not paid by any of the manufacturers I am advertising, this is an Amazon thing that if I help sell anything via their website they give me a little something for it. With my 3D model sales, I was saying what I had used to help make a model and therefore helping the likes of Amazon sell items, but I wasn't getting anything for it and that's the only reason I signed up for Amazon association.
