Two versions of a compatible with DKL units filter. I had the problem of old filters corroding quite quickly because of heavy use of hypochlorite, and DKL could not get another filter type that would endure hypoclorite. At the time it was printed by SLS with Nylon. The filters are now 3 years old and have endured a lot of chemicals, blood and products. They are aging fine with the materials.

I have not tested with FDM or SLA printing, so I can't tell you how they will print with these techniques. I would recommend a chemically and high temp resistant material if you want to autoclave them. 

Included are the CAD files if you wanna change stuff. They are quite old, and I was not as tidy back in the day.

Enjoy !
