USB Powered Vacuum

This is my attempt at making a USB vacuum cleaner for my office desk and keyboard.
I used a 5 volt radial fan from an old laptop as that is what i had laying around.
It hasn't got the worlds best suction but for what I want it for it is ok.
Everything apart from the fan, usb lead and 2 small self tapping screws is printable and simply pushes together.
It should push together with a snug fit but may need a bit of a sand in a couple of spots if its a bit too snug.
For the filter, I use a small bit of nylon stocking stretched over the filter retainer. The stocking screen is held in place by the small clearance between the filter housing and the retainer.

I hope this comes in handy to anyone willing to try making their own.
