This is a small oil diffuser.  I had extra fans and thought why not.

The model has a lid that can be glued on and one with groove that just sits on top. See Below for screw hole information.

Make sure to test your fan have it pull from bottom and blow up across the wood.

There is a model without the micro USB so you wire anyway you want. See picture and text below if you do use a micro USB. 

This uses wood diffuser to hold the oil.  The fan just moves the scent around.

There are 2 holes you can use the 3mm screws that came with these fans. There are also 2 holes for 20mm screws and nuts. ONLY USE 2 SCREWS.

Fan 40x40x10 Most fan should work (5V 0.1A) This one is nice and slow.

Power

I used a micro usb connector just solder and super glue. See above pictures for wiring. Black or negaitive(-) goes to GND. Red or positive(+) goes to VBUS. The 5V cube is a (5V 1A).

You can wire direct to a USB A cable if you want. Why USB A you ask then you will not screw up the 5V requirement for the fan.
