Matrix Precision Bed Cable Chain Attach

I printed a cable chain for my bed heater wires (This one: http://www.thingiverse.com/thing:2067601) and needed a way to attach it to the bed. This seats in the thermistor groove along the front of the Matrix Precision upgraded bed for the Printrbot Simple Metal.

The model uploaded doesn't extend quite as far as the one in the picture, but be careful you don't crash your hot-end.
