Fish tank water change filter

I have been using a sponge filter for my aquarium for a long time to protect my shrimp and small fish from harm when I change the water. However, I found it to be less effective.

That's why I decided to create a new filter using PLA material and a 0.4mm nozzle. It works quite effectively and ensures the safety of my aquatic pets during water changes. If you have any questions, feel free to reach out to me. Also, I'd appreciate it if you could take some pictures of the filter. I hope this innovation can be helpful for fellow aquarium enthusiasts.
