Fridge vent cover

grabcad

meant to be printed in vase mode with large extrusion width for minimal material use and strength(the ribs alternate between the top and bottom ones so the printer always does only 1 perimeter per layer, no support needed as long as cooling is good enough for 30mm bridging) to reduce dust getting behind the fridge as well as cooking splashes since there are stovetops next to the ventsthe vents shape follows the not very straight cuts we had to do using a dremel because of constrained space and lack of better tool
