Gain 3.2mm more clearance for modified fan ducts with the 1.6mm tall ultra low profile heat bed cover. To gain this clearance the wires are relocated to the bottom side of the bed using special hardware, listed below. If you don't need this much clearance there is a 2.2mm tall option that provides 2.6mm more clearance and uses more typically available hardware, see details below. You will also want to trim the bed alignment studs accordingly for either option.
