CR Spotless Centering Ring

My CR Spotless water system came with some 3d printed spacers and one of them broke. I checked their website after I had ordered some new replacement cartridges and it would have been $8.00 each and delivery fee plus state robbery, so ended up just making my own version, that works just fine. Was able to quickly print 2 of these using PETG and they will last a lot longer than the thin ones that came with it.

Slide them down a few inches over the cartridge before putting in the enclosure.
