Pet Water Fountain Filter refillable - Fofnon brand

I didn't want to buy the over priced filters for my pet fountain so this is the solution I came up with. There is a photo of the fountain above and I will add a link below. 
 

 I recommend using PETG for printing this model bc of how well that filament does in  water.  I enabled auto-support bc of the center span. 
 

I use aquarium activated charcoal and it works so much better than the filters that come with this product. It’s night and day. I had a test version of this model and I just dropped it in the tank for more filtration.
