airplane wheel hub

This is a hub I made for some foam holiday wreaths from Dollar Tree. They came out good with the total tires coming in at 16 grams each. I used .16 layer height, 2 walls thick, 4 layers top and bottom, 15% infill. They are for a 50mm inside hole on the wreath/tire. Feel free to modify to suit your needs.. 2 hubs per tire
