Mazda 3 Winter Tire Center Hub Cap

thingiverse

Winter steel rims do not come with center hub caps, and I believe none are available at a reasonable price. I wanted to hide the heavily rusted wheel spindle hub assembly and prevent further exposure to our heavily salted roads. Mazda 3's have a five-lug setup with a 4.5-inch offset and 21mm nut. I designed center hub caps and wheel nut covers as separate pieces so they could be printed on my small 3D printer bed and easily replaced if damaged. Five wheel nut covers friction fit onto the lug nuts that hold the steel wheel rim in place, then slide into grooves in the center hub cap to hold it in place. A light tap with a rubber mallet on each wheel nut cover secures everything in place. Removal requires a small pry bar placed under each nut cover and a gentle upward prying action.
