Digitrax Single Case for UR91 etc

Wanted to make a case to keep the dust and dirt out of my Digitrax LOCONET controllers and receivers. I've never liked seeing this mounted to the side of a layout without any real protection for the electronics behind them. This is the first case, I'm currently designing a rack mount system as well as a multi unit stand alone case.Can be used with heated inserts or just screws.
