My riving knife is only *slightly* out of parallel, and I haven't really bothered to fix it since it does not appear to affect my results.? I have a 3D printer and printed that replacement block, however it didn't come out super clean for me so I have never bothered to try to use it.

The only problem I do get with my riving knife is that one of the bolts that holds the mounting bracket in place will loosen over time, which results in the knife being wobbly.? When that happens I just have to go back in and tighten up that bolt (it's just behind the belt close to the blade arbor).? One of these days I will attempt to put some lock tight on that bolt... of course I've been telling myself that for years.
