ISO standard fire lizard

i took another crack at the drum scanner mechanics. i managed to get a lot of the really big distortion artifacts out but so far that's mostly just let me see the small distortion artifacts. i think i'm gonna have to put this one on the shelf until I either come up with a much more reliable way to 3D print the drum spindle or get access to a lathe somehow (if nothing else i think it's decently likely i end up buying one early 2023)
