Adjustable Captive Fan Vent

Remix of a vent cover to better suit it for my needs. The threads are now bottle threads as they're better suited for 3D printing. Also added a captive bolt with a left handed thread so that the cover can't be fully removed.

Printed in PETG with 30% infill and 0.275mm layer height

Made for use with #8 countersunk woodscrews
