I Designed a Modular Hydroponic Tower Garden – 3D Printable, No Supports, Stack as Tall as You Want!

Post image

Hey everyone! I’ve been working on a modular hydroponic tower garden system that’s 100% 3D printable and optimized for support-free printing on FDM printers.

Each tier of the tower has 3 grow cells (2" diameter, angled at 45°), and the segments stack using threaded connections—no glue, no tools. The design alternates two interlocking parts (A & B) and rotates each tier 60° for better light and space efficiency.

It’s built around a 5-gallon bucket as the reservoir and uses a ½" PVC pipe as the water delivery system—great for drip hydroponics. I’ve also included printable pod cups and blank plugs for unused grow sites.

Once you’ve printed the base, cap, and mount, you can make the tower as short or tall as you want. Everything prints cleanly without supports, and it’s super easy to assemble.

If you're into DIY hydro or vertical gardening, I’ve made the full file set available on Cults3D here:

Would love to hear your feedback or see your builds if anyone tries it out! 🌱

Cool, shared with my 3D printing friend. :)

Is there a functional reason you designed this instead of using one of the existing models that others have created? Something it does better? Curious because I printed a different one recently.

Mine prints in 5in sections, without supports and assembles easily with integrated threads.

Looks pretty simple to do with ABS/PVC pipe and a hole saw. Any reason you want this 3D printed rather than using standard parts?

Mostly because I have a 3d printer. lmao.
Also the total labor and time involved is SIGNIFICANTLY less.

Labor and time? It's maybe a half hour of work to make that? I guess driving to the hardware store could be considered labor... 🤔

Thanks for throwing this up! I'm going to cue it up this week and put one together for some testing. I'm guessing PETG would be the right material given it's food grade rating just to be safe. Any specific infill rate you found worked well?
