Sooner than expected I'm suddenly the proud owner of an E3d ToolChanger. Because I'm planning to do the wiring myself, I didn't buy the wiring loom. Unfortunately, the metal stripes come as part of the wiring loom, these are a kitted item so aren't available separately. I'm planning to buy the stripes ensewhere. Can anybody tell me what the dimensions of the stripes used in the ToolChanger are ?
