The printer didn't come with a lid, so why leave all those other covers and doors on it?  It sure is a lot easier to get to stuff, and it seems to enjoy the fresh air to be honest.

Printed in generic PLA with standard settings, upright, no supports, 10% or 15% infill of your choice.  I did 5 wall loops because the threads for the 6mm straight-thread air fittings are printed.  They come out a little chubby so chase them with a 6mm tap and don't overtighten. You could add a drop of super glue to the threads but I didn't.

Attached with the stock fasteners that came with the machine.
