Hose adapter for "Juwel Eccoflow" aquarium pumps

thingiverse

My old aquarium pump had reached the end of its life and needed to be replaced immediately. Unfortunately, none of the available pumps were a direct drop-in replacement for my existing setup. Undeterred, I acquired a new replacement pump that would allow me to upgrade my system's performance. However, upon inspection, it became apparent that the new pump didn't share the same mating surface as the old one, making a seamless connection impossible without some creative problem-solving on my part. To rectify this situation, I fabricated an adapter to connect the 12/16 filter hose (with its 12mm inner diameter and 16mm outer diameter) to the "Juwel Eccoflow" pump. This adapter is designed to provide a secure connection between the two, albeit one that relies on friction rather than a precise mechanical fit. While I'm confident in the overall functionality of this adapter, it's worth noting that a friction fit may not be entirely leak-free under all circumstances. Nevertheless, with proper installation and regular maintenance, this setup should provide years of reliable service for my aquarium.
