Scalextric Cable Holder

This is designed to clamp a cable to a half=straight piece of Scalextric (UK Slot Car) track
I needed a way of securing a power cable to the track for the pedal powered scalextric systems I build.
I made this connector which works for me. You need to cut away the edge of the scalextric track for this to fit, which I do with a Dremel tool.
It clamps with two M4 machine screws (and nuts) and two M3 machine screws (and nuts). The nuts are embedded in the base of the unit using a soldering iron to heat.
