Reddit reviews Rubber Leg Tips Black, 1" 4-count

I used this as well. Threw on a couple rubber chair tips (Like these) to angle the board and stained the shelf with a bit of leftover stain. Easiest thing in the world to do, and it looks great!

Airflow is a game changer, even if you don't use a fan. See if you can get space between modem/FW/SW.

Another DiY option - using a power drill. Made it myself using these leg tips, purchased from Amazon. I found rolling the paint less of a mess than shaking them as shown here.

Nice work! After finally making the jump to salt, I've become a firm believer in fighting butts. I gave a little thought to something like what you've done here, but I finally decided that I'm too lazy and ended up buying a bunch of rubber chair / table leg stoppers like THIS. They do fine once you find the right size - if nothing else they keep your end caps from getting scratched up.

Yes....I put one on my 2wt. So there.
