This is a functional desk model of a shrouded ducted fan, based on odie_wan's original model.

Up-scaled to accommodate 2x 50mm fans and rotated to ensure fans vent to the rear. Removed the flat bottom and designed a simple display mount to route the power cable through, with keyed fittings for stand and bottom of shroud.

My finished version used simple 3mm screws to hold the two halves together once the fans were installed. Printed in blue ABS and blemishes, square alternate wiring hole on side was filled with ABS sludge, the shroud join was patched with ABS sludge and then all sanded back down prior to painting. Painted with aluminium spray paint, lightly sanded and then finished with clear gloss.

Note that in my completed model, I used ABS sludge to fill and hide the middle join and the square cable hole on the side, before preparing for painting.
