Better filter for hydroponic tower

My Ultimate Upgrade for the Hydroponic Tower With this upgrade, made from a 120 mm spacer, you can easily filter the water in your tower.Anyone who has used a tower like this for a while knows the issue: no matter how careful you are, dirt and debris from outside always find their way in. Normally, you'd have to go through the hassle of draining the tank, disassembling the tower, and emptying the bucket. But with this upgrade, that’s a thing of the past.Inside the small drawer, you can install any filter of your choice. It can easily be pulled out, cleaned, or replaced at any time — super convenient! Additionally, I integrated a 15 mm hole with a slight overhang into the 120 mm spacer. This allows the water hose to be routed into the tower from the side, since the bottom path is blocked by the filter. I inserted M3 heat-set nuts into the drawer and used a square plate to clamp down a filter of any fineness.You're free to choose your preferred filter. Note on my print settings!
