Hello,
Sometime ago I purchased one of this: https://www.adafruit.com/product/275
I really liked the product but I specially liked the rubber feet that came with it (they appear to have some kind of nonslip coating), I liked those rubber feet so much I want to get some more of the same and other sizes for some other projects I have going on.
Would it be ok for someone from Adafruit to share where I can find those rubber feet? By the way, I tried McMaster-Carr (https://www.mcmaster.com/catalog/8771K81) but the ones they had are not as good as the one you have.
Thank you.
