Bubbler bird bath

I made this so I could have a shallow bird bath that I did not have to refill very often. Water will flow out until a shallow level is reached in the spackle bucket lid is reached stop. When the water level drops it adds water.
The band around the 1 gal. jug is needed to prevent the jug from collapsing. I printed the band in PETG so I could use a screw to tighten it..
The main piece is the only piece that need supports.
