Hydroponic Tower - Complete (Revised)

I downloaded the original from here, but some things were missing and the print settings were not quite to my taste.

Now that I have finished the tower, I would like to share my findings with you :)

In the original, all wall thicknesses were specified as 4 in the first print profile - but for most parts, 2 walls are easily sufficient. I would only recommend 4 wall thicknesses for the pot lid, as this is where the entire weight is borne.

The file says that it fits a 24cm pot - but I bought one with a 28cm diameter at the DIY store. I simply went to the store with the printed lid and tried out where it would fit best. Snap fit :)

The original file contains the 4x-planter with ugly wrinkles (artifacts), I have added a nicer file here so that you don't have the same mistake as me :)

I also added more caps and made inlays for them. So you can print them in a different color and then just press them in, fits wonderfully. Otherwise a light tap with a small hammer.

If you print a 5x-planter, the name tags will no longer fit. They are simply too wide. That's why I drew new ones and added them to the file.

In addition, all the plates are filled up so that the printer is ideally occupied. If you need less, simply delete them.

My recommendation is (everything with 2 walls except the lid):

- 6x the 4x-planter - 1x 120 spacer at the bottom (filter inside) - 5x 40 spacers - 24x small pots (4-5 way, enough) - 1x Dispenser+Lid - Lid made of 6 parts (with 4 walls!) - 24x normal tag holders (if needed) - 1x Water Cap - 1x Energy Cap (your choice)

I am also happy to share my Amazon purchases with you here. I'm from Austria, so the links are from the German Amazon and not the American one, like most of the others :)

- 12 x cheese head screw (cylinder) M6 x 25mm (stainless steel) (pls drill out the printed holes!) - 12 x nut M6 (stainless steel) - 24 x washer M6 (stainless steel) - 6 x cheese head screw (cylinder) M3 x 16mm (stainless steel) - 6 x nut M3 (stainless steel) Edit 8.5.25: PLEASE be AWARE of potentially wrong translation!

I've created this site in english, if you are watching it in another language => SCREWS !

M6 x 25mm Cheese Head Screws are this! (German: Zylinderkopfschraube) NOT COUNTERSUNK!

I used just under 3.5 kg of filament in total. As you can see in the picture, I used 2kg of PETG Stainless Steel and 2kg of PETG Lime Green .

For example: If you print a 5x-planter with 4 walls instead of 2 walls, you'll need 320g instead of 219g of Filament. That makes a difference in terms of quantity :)

Happy Printing!

The User @user_3194745930 made a Lid for 30cm Pots (ACE Buckets) => File can be found here.

Would be nice if anyone could give some feedback :) Thanks

Because it is asked VERY FREQUENTLY :)   FAQ

- The exact pot i‘ve bought: Scheurich Übertopf 920 Ø 28 cm x 25 cm Dark Stone But: Print the lid, assemble it and go to your local store and try it. There were 5 pots of this model, and it only fit on 3 of them. The other 2 pots were not exactly round :) - I recommend that you drill once through the M6 holes of the lid, because a printer usually never prints exactly round. Sometimes the screws are a little difficult to get through. So drill through the holes once with a 6 mm drill bit, then it can be screwed together very easily. Connect all 6 parts with two screws, 2 nuts and 4 washers each.

- The filter (with a mesh) is to be built and used as follows: The first print plate shows “Filter+Spacer”. Take these two rings, clamp the mesh between them and screw them together with the small M3 screws. Then punch a hole in the middle so that the hose can be fed through. This filter is inserted into the spacer, and this spacer forms the basis for the tower, so it goes right at the bottom, just above the lid. The filter is intended to protect the water - and therefore the pump - from any dirt that might fall from the plants above. I didn't take a picture of it myself, but some users ( Codybkid69 ,   BokuNoMaxi ) in the comments were kind enough to do so :) Pic#1 and Pic#2 Edit 29.07.2025:

I pinned a comment from @Baladauf , who found a few cheaper alternatives on Ali. To clarify: my shopping list is what I considered to be good and bought. That doesn't mean you have to buy exactly the same stuff :) Everyone is free to shop at the retailer of their choice.

Thanks @Baladauf !

I pinned another comment from @dakater . He was kind enough to make a tower spacer for those whose tolerances are too large and whose tower is therefore a little unstable. Please let us know if you try it out :)
