CR Spotless Centering Ring

The centering ring for one of my DIC-20 cartridges broke. The original is clearly 3D printed as well, but quite thin and flimsy; this design fills the full height. The measurements aren't exact (CR Spotless didn't respond to my request :( ), but it's close and fits in my unit. The pictures show both the green PLA test print compared to the original, as well as the final gray PETG installed alongside the original. You can sort of see that the ring fits more snugly, there's no gap
