Build Video: 

Everything can be printed without supports.

The only thing that should be printed a little different is the bottom most screw funnel. You should print it on a 45 degree angle so that the layer lines aren't a weak point. That will require supports being used when slicing.

The Slatwall Hooks slide right into the base, optionally can connect a hose directly to the top, or use the buffer to have multiple rows and not worry about the planters overflowing.

Update 2025/02/20: I've added the Fusion 360 and Step files for this build. I've also added an updated Cup that has a little more support at the end to help with some weakness.
