Working Bubbling Chest *Automatic*

Bubbling chess for fish tank:

This design was inspired from the Better Call Saul series, where Saul has a chest in his fish tank that opens when filled up with bubbles. Now, you can 3D print your own!

Video showing Saul's fish tank:

This chest has three pieces, the bottom part, top part, and a small amount of standart filament:

• The bottom part is printed upside up, there are three models available for it, some containing holes to insert an air tube and inser the bubbles in the chest:

• The top part is printed upside down, it has some small overhangs, you could support them, but printing with not supports should also be fine.
• A small bit of filament is also reqired to complete the hinge as shown in the image below. You can stick it in the sides witha glue gun or stron glue:

As observed in the video, some weight should be added both inside the chest and on the lid part (either outside or inside) to avoid the whole chest from floating and help the lid close.

I have made little testing to this design due to a lack of time, feel free to improve it and give feedback on it. Scaling it should also work nicely if the hinge is adapted.
