Piggy Bank (money meter)

Parts needed:

You only need to print each model once, in total there are 7 models.                                          You will also need a few materials that cannot be printed:

• 2x elastic rubbers
• Some glue

Assembly:

1. First, you glue the 3 different pieces of money levels to the side of the body. The order from top to bottom should be: $ - $$ - $$$.
2. Then place the two rubbers onto the hooks of the inside of the main body
3. Then slide the base inside the body through the rails. Please notice that the base has 2 hooks. These hooks are for the rubbers, and they need to be facing down. You need to place the rubbers there. The base should be held by the rubbers.
4. Next, you just need to glue the arrow at the end of the stick from the base. The arrow needs to be facing the money meter
5. And last but not least, you simply have to close the piggy bank with the top part.

Update: 

Added a second lid with higher tolerances
