i dont think you'll do this

if you assemble the workable PE hinges, you can't really play with them, ultimately they break. to make them more durable use a drill as the stock to roll the hinges on, after wards flux and solder the hinge after it cools remove the drill bit while twisting it, repeat for the other side. now if you are a kid at heart you can mess with it. p. s. you might have to file or sand the parts to fit but they are definitely more durable
