Cascading Waterfall With Koi

UPDATED: i noticed a couple issues with my design and fixed them
things includes making the koi fish have small holes in bottom to attach to the base bowl supports that i added
This is a build I put together but have not printed. If you happen to print this please share with me the results. Thank you and I hope you enjoy this.
The tall tower has a hollow tube so that you can run a water pump line up and the base is hollow so you can hide wires.
UPDATE: thought it may be easier to print the posts separate so I added files with them Separate. Also the KOI do not have supports so i made it so those can be printed separately also.
