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 by side on the bottom of a typical 5-gallon bucket.  I plan to design a mount style that will able up to (4) to be added to the bottom of a 5-gallon bucket, and I'll update this project with the additional file if I ever get around to making that new version.
 

Model Info:  

2in (50.80mm) Straight Adapter - Diameter should be 96mm at external wall, 50.80mm tall

13mm Mount Adapter - Diameter of mount should be 122mm, diameter of adapter should be 96mm at external wall, 13mm tall

Print Settings:
