Fan Shroud for Ender 3

This is a two-piece model to cover the control-box fan inlet on the Creality Ender 3.

There is also a one-piece version; it will probably have to be printed up on end to print without supports, and it will be a bit top-heavy on the print bed. Print it lying down for greater stability if you don't mind taking the time to clear all the supports out of its guts.

There are rectangular cavities in the flange of the shell component to accept magnets of up to 10x5x2mm.
