Cut a piece of wire hanger to your desired length. This will vary depending on the size of the tin.

You are going to bend the wire to fit as flush as possible in the tin, and have two notches on each side to hold the rubber band in place (see picture)

I used a pair of pliers and a small vice to get this step done. You may need to try a couple of times to get it just right.
