Works well and the kids love it.

I printed this with no supports without any issues. I specifically tried to design the breather hole to avoid supports. The printer should have no issues bridging the gap.

I did apply some wood wax oil with a small paintbrush to the bottom compartment DURING PRINT to make the teapot water tight. Not sure it's needed, but I had wax laying around and decided I'd try it and it's not leaking :)

It's also possible to add a liquid sealant post print!

As you can see in the pic, the fluids are visible through the PLA, maybe try increasing to three walls or print in darker colors. I ended up spray-painting this print.
