LRF-compliant desktop interface
If you're able to pry off the LRFs (Little Rubber Feet) without dirtying or damaging the sticky stuff & without leaving any sticky stuff behind, you can use a clean backing sheet for stickers or peel-off stick-on labels to keep the LRFs clean & easy to peel off when it comes time to put them back on the computer.
Make sure to peel off any sticker chaff first if you use a sticker sheet. You don't want to stick the LRFs to any sticker parts, only backing parts.
