Gasket for 6-way shower diverter cartridge

thingiverse

I had this shower diverter that started to leak. Found that it had a rectangle-shaped profile of the gasket ring, which will be difficult to find. Replacing the entire cartridge costs £200+, and besides it is no longer available. So I had a roll of Ninjaflex, and gave it a try. Tested a couple of different sizes. The inner diameter is 44mm, but I ended up printing ID=42mm so it stretches a bit. Also made it a little bit wider than the original, and a little thicker. Anyway, the second attempt worked nice and I no longer have a leak :) For print settings - see attached Cura project. I printed with slow speed 15mm/min but kept a little retraction even because my Bondtech extruder seems to handle that well even with Ninjaflex. Used 4 layers bottom/top/walls so no infill needed as there is no space for it. Not sure if anyone actually will use this gasket as is for the same purpose, but maybe you wonder if it is possible and what print settings to use. The answer is yes, and look at the attached Cura project. Good luck! Made in Sketchup 2016. File also attached.
