Use some glue to fix aluminum foil to the bottom of the negative pole. Then press it into the negative pole holder to shape it. Wait a little. Remove the negative pole from the holder and use some glue to attach the aluminium foil to the contact hook. Remove surplus aluminium foil with scissors.
Although all parts are identical, I found one cap harder to fit to the battery housing after printing it. I use this side for the negative pole and the other side for plus and to change the batterie.
Glue might not be necessary but it makes the aluninium foil more durable.
