Yes and no - mine had spiral wrap that ran along the left edge of the bed, but none on the wires coming out of the electrical box. I found some 1/8" spiral wrap at Home Depot, and used that the wrap the loose white wires and the brown wire together from the power supply up to the Panduit. Seemed to work just fine.
My mat wasn't drilled either. What I did was go ahead and attached the mat to the bed, then I simply flipped the bed over and used a #11x-acto knife to cut multiple slits in the mat thru the holes in the aluminum bed. The mat was easily to cut, and the screws went right through.
The ceramic heater is a loose fit in the hot end.I am going to wrap the heater with aluminum foil for a better fit. Can thermal paste be used on the thermistor for a better fit?
