The rubber foot on the bottom of my rMBP is damaged. How would I go about getting it fixed?

Those just push out from the inside. I buy them off eBay a dozen at a time but you may be able to just get a couple. I also put a couple of drops of super glue on them when seating. There is a small dot that aligns with a corresponding hole on the rim. Here’s a set of four for $2.70 & free shipping: http://www.ebay.com/itm/4-pcs-New-OEM-Ap

I removed all 4 feet, cleaned those areas w/alcohol, and attached self-stick round felt pads. Worked so good that I put another one on top of the original felt pad for added height. This allows the computer to run cooler, I think. You can get a pack of white sticky felt pads at Lowes or Home Depot.
