3D printing a self-cleaning water filter sounds interesting, I guess. It's about collecting rainwater and using this Coanda filter thing, which is supposed to help separate debris, similar to what they use in hydroelectric plants. Not sure how much cleaning that actually saves, but it’s better than doing it manually, right? Anyway, if you're into water filters and all that, maybe check it out. #3DPrinting #WaterFilter #SelfCleaning #Rainwater #CoandaFilter
