This little clamp supports the wires comming of the heated bed, it otherwise is only held in place by the kapton heater. On my Aluminatus this caused the kapton heater to seperate from the alu heat spreader.I've printed it in ABS with 0.3mm layer height and 33% infill without any problems.You'll need two M3x6...M3x8 screws to clamp both parts together, the lower part has slightly smaller holes so that no nut is needed. Use a tyrap to hold the wires in place.Place it on the bed frame adjusted so that the wires under the bed run just along the side of it, and lining up to the U part of the clamp.
