Rubber Feet

Hey there folks,

I have a few Palmtops that need new rubber peices on the bottom to grip the surface that I am placing the unit on. Im looking for 3-5mm round or square and 1mm thick. I cant seem to find 1mm thick, I dont want to go higher than 1.5mm as I want to be able to slide the unit back into the docking station. Didnt know if anyone has purchased anything that matches my description and where it was purchased.

Thanks

-Walt
