To answer your question, caster cups are those semi-flexible things you put under chair or table legs to protect your floor surface. I used 1 3/4" "Super Sliders" from Walmart. I used one for the mic element gasket and one for the grill which I drilled holes in and painted. They were shaped to fit with a Dremel. I was pleased with the results and they are cheap.
