Honestly having it spinning at ludicrous speeds with no safety guards except a smile is a little terrifying. If I was going to do that sort of thing with any regularity I'd print an enclosed unit instead.
That is interesting. I think I'd find a big can or such to contain it. I respect your curiosity: I just made a seismograph for fun.
