40mm fan grill / cover / guard

This needs print support (to reduce additional noise turbulence by having the "grill" further away from the fan blades), I used hybrid trees with 0.2mm interface, and 80% line width on support which helps separate it. followed by a bit of cleaning
Not the easiest print but not impossible either.

I tested in PETG at 0.1mm layer height.

Screw holes are for m3, as that's what I use on my shroud design (ApolloLander on Patreon or basic free model on Printables)

what it looks like in front of a noctua
