I've made parking stands out of hardwood dowels(closet pole) or old shovel handles. They break rather than bend and are simple and inexpensive to replace. For most implements, you don't really need a foot, but if you want one, you could use a fender washer or, if you really want a big foot, a electric box cover. For my snow blower, I left the D handle on the shovel shaft so that the stand doubles as a blower chute clean out tool.
