Do you just buy more of the footpads online or have you figured out a more permanent solution? I pack mine up and travel with it frequently, and the rubber feet are always coming off.

3 went off so far... maybe I should try a proper glue for them? It is not like I have any reason to access the screw behind, and if, I can always cut the rubber away somehow.

This said, it is nothing exotic, the M3 m9448A is the number for rubber feets. It just difficult to buy it a non-industrial amount.
