Thanks for the advice @markevans36301! 
I considered acrylic but I only have clear right now and I hate waterspots. The curler and shaver never get wet so I think they’ll stay ok. Plus the curler barrels can get hot so wood seems safer than plastic on that one.
On kerf: they’ve seriously not implemented that yet? I mean I know passthrough alignment is still in the works but Dan mentions auto kerf being on the roadmap all the way back in 2016!
