A three-dimensional (3D) printer build material spreader cooling system may include a build volume, a build material spreader, a spreader drive, a spreader cooler and a cooling fluid supply. The build material spreader may have a length and a first fluid conduit extending along the length. The spreader drive is to translate the build material spreader across the build volume. The spreader cooler is in thermal conductive contact with the build material spreader. The spreader cooler has a second fluid conduit extending along the length. The cooling fluid supply directs cooling fluid in a first direction through the first fluid conduit and in a second direction, opposite the first direction, through the second fluid conduit.
