Universal Grow Light Arm Mount for Hoocho Modular Tower (100% 3D Printable)

I really love Hoocho's designs and have multiple towers running and producing leafy greens indoors; however, I did not want to order various parts to create a light solution, so I designed my own 100% 3D printable solution instead.

Designed for the modern indoor gardener and maker, this modular arm system offers a zero-tools, zero-metal, fully 3D-printable solution to mount grow lights around the Hoocho Hydroland-compatible Hydroponic Tower.

Description

Easily and cleanly attach LED grow lights to your Hoocho designed, hydroland-compatible hydroponic setup with this versatile, modular arm mount system. Designed specifically for home manufacturing and optimized for popular vertical LED light bars like Barrina (and many global clones), this design requires no screws, bolts, or extra hardware — just your 3D printer and a few zip ties.

Key Features:

Zero Tools Needed: No metal hardware. All connections snap or slide in place.
Fully Modular: Arms come in three tested sizes — 50mm, 100mm, 150mm — and can be combined for custom length.
Flexible LED Compatibility: Works with most vertical LED strip bar lights. Just zip tie and go!
Strong & Lightweight: Engineered for PETG, ideal for environments with UV exposure and moisture.
Universal Fit: Designed to fit the Hoocho Modular Tower cap — or remix for your own build.
Upgrade Path: Optional heavy-duty base mount included for heavier or larger light bars.

What’s Included:

Top cap with 4-arm socket
Three arm lengths (short, medium, long)
Light clip system for easy zip-tie attachment
Optional heavy-duty lower support base
Example configurations and photo references

Assembly & Usage

Print the cap, arms, and light clips in PETG (recommended).
Snap or slide arms into cap sockets.
Secure LED lights using zip ties through the provided channels.
(Optional) Use the base mount for added vertical stability. (separate file)
(Optional) Horizontally printed M8 screw is included as a separate file to reduce the chance of snapping the screw while tightening.

Pro Tip: Use a mix of arm lengths to fine-tune your light placement around the tower.

Tested With:

Barrina Grow Lights (and rebrands), 2, 3 and 4ft versions.
Hoocho Modular Tower (3D-printed hydroponic tower)
Standard zip ties
Printed in PETG on a BambuLabs A1 and Elegoo CC

Notes

This solution includes the arm and cap assembly only — the tower and lights are not included.
PETG is recommended for moisture and UV resistance, even for indoor use.

Could use some refinement, but it printed nicely. Plates should probably have as many as can fit on a plate or as is needed. so 2 sets of arms per plate and all 8-12 of the bolts/nuts. Good model! Thanks!

@twisted.bypass

thanks for posting this! In the process of printing hoochos tower. I noticed you had both hoochos tower and the boundarycondition 3d printable modular tower. you have a preference between the two on which one is better? I finished printing boundarycondition variant but does not seem to do well at evenly dispersing the water.

Glad I could put it online. Great question. I like the Hoocho Modular Tower better and have switched to it moving forward, but I do believe that Hoocho should add a locking mechanism to the 3D printable version, specifically to the top and the base, so that the tower pieces could be held together. In moving my Hoocho tower, I almost lost it all and had it topple over. Along the same lines, I've also had heavy plants start to pull out the root. Outside of that one issue, I like it more. It is easy to take down and put back up, and it has plenty of space for a big root system. With that said, both towers have been very successful for me growing leafy greens. Here's what all 4 look like.

Replying to @user_3912475227 :

@M1ckeyDs

I remixed it and will post a profile soon for the Juice Plus Tower Garden Flex garden.

@kblagg

I tried posting my remixed version but it says your license type doesn't allow it. Is that something you can update? Would prefer to post it and give you credit for the original design.

Thank you so much for this! I made an adapter for another hydroponic tower with 6 arms. Am i allowed to publish it with mentioning these arms?

5 stars for the appearance The screws occasionally snap off but I am otherwise satisfied so far I still need to put it into operation but I have printed the system for two towers
