This Vacum cleaner is design to be operated with a 9V battery, it's portable so you can carry it in your car or office and clean all the dust.

This Vacum cleaner has a particular design that shold prevent any sucked dust to escape back once it has been sucked into the vacume cleaner

Here is a list of anything that you will need:

My 3D printer is the Original Prusa i3 MK2 and the clearance of the project worked just fine for me. If you need to adjust something there is nothing that can't be fixed with a bit of sand paper.
