Fish Filter Diffuser

thingiverse

Apologies to all the serious aquarium enthusiasts for referring to this as a "Fish Thingy". I created it for my sister and I'm not an aquarium owner myself, so take it from someone who's just trying to help. This diffuser is designed to prevent high fluid flow rate filters from pushing fish around. After conducting extensive long-term testing with PLA in water, I found that there was little to no degradation, although PETG might be a safer alternative. Considering this and the fact that PLA is food-safe, I'm confident that it won't harm the fish. This model has its limitations, but some people have asked me to share it, so here it is. If anyone wants to improve it, I'd suggest making the following changes: 1. Increase the diameter of the holes from the filter to reduce friction. 2. Tweak the clip geometry (the filter this was designed for had mostly curved surfaces, which made tight-fitting geometry challenging).
