Nice, nice. I picked up one of the CT rotary tool kits for like $15 on sale a while back. The plexi cutoff wheels were worth it alone. As for something I was thinking, maybe just cut a rectangle out of the side of the shroud, instead of trying to do holes for the tubes. I think it's be too hard trying to get a clean circle in plastic. (Or if you were thinking of doing that already I'll shut up

)
