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.

The use of brims is recommended on all parts.
The motor body, motor cap, filter retainer and nozzle do not need supports.

Print the nozzle small side down without supports.

The filter body and motor mount will need supports.
Print the filter body small side down with supports enabled everywhere, not just from the build plate.
