ZeroWater Filter Adaptors

We had a need for some really clean 0-ppm water, without the expense of gallons of distilled water, for a hobby project. We prefer the ZeroWater filters due to the gravity feed design, slow passthrough enabling consistent 0-ppm, and they are rebuildable with bulk source material. The issue is we typically filter 28+ gallons of water at a time, and doing that through the ZeroWater pitcher at a rate of 1-gallon at a time was not efficient. We needed to be able to add at least a 2nd filter, and we needed to be able to filter in batches of 4-gallons at a time.

Unable to find a ZeroWater adaptor or filter casing design uploaded anywhere, I built a rough one within the constraints of TinkerCAD. I've included (2) styles at the moment; one is just a 2in (50.80mm) straight adaptor so anyone can tailor it the size and usage that they need, and the second is the same adaptor trimmed down to 13mm tall and a 0.5in (13mm) mount plate added. The mount is sized so that (2) of them can fit side b
