“I designed it on solidworks then 3D printed a model. Used that model to make a 4 piece plaster mold. Used the plaster mold to slipcast the final part then fired and glazed. The two stainless pieces I had a local metal shop make for me. There is a pump below the plastic filter housing that cycles the water through the filter. And yes it does filter, much better than ones you can buy on Amazon or at pet stores, which is why I started this project to begin with.”
