Vent register fan

This fan is designed to attach to a 4"x12" vent register and help boost air pressure. It is split into 2 models so you can print it on smaller printers (6"x6" or 150mmx150mm or larger print beds) I would reccomend printing this on a raft or putting ears on the corners to prevent the corners from lifting off the bed.

The fans I used are super quiet so I decided not to put in a potentiometer or a switch to control the fan speed. I have included the freecad file if you want to modify it.
