Quoted from Mitch:Any chance you can do the time expander cover for doctor who? These are impossible to find, yet aren't that big and look easy to make. I could even ship you a slightly broken used one if we couldn't find one closer to you.
They were reproduced once by twistedpins which is no longer in business and they weren't made well and broke quickly.
I have an HUO Doctor Who and would be willing to loan out my undamaged expander cover for molding if needed.
