This model is a replacement foot for an Eames molded chair. Attached photos show the original part for reference. Print out 4, push them on and you're good to go. I might try printing this out in Recreus filament to make it safe for all floor types. Print out in your favorite material. There's nothing terribly tricky about this print. These are push-to fit parts, and I got them on by popping one on the chair leg and then sitting down on the chair to press them together.
